Happiness is a butterfly, which when pursued, is always just beyond your grasp, but which, if you will sit down quietly, may alight upon you.

Brushfoot butterflies are ubiquitous in Connecticut, familiar to most people who spend any time outdoors in the summer. Almost one in every three butterflies in the world is a brushfoot. Members of this subfamily of butterflies, the Nymphalinae, differ from other butterflies in that their forelegs are well shorter than the other four legs and are not used for standing or walking, These forelegs have little brushes or hairs rather than feet, thus the common name, which they use for tasting and smelling. The next time you see a monarch, check out its front legs.

Many brushfoots are found in particular habits, common ringlet, which prefers open, sunny fields with plenty of flowers like goldenrods, fleabane and asters. Others may be found along open wood lines, like question marks, commas and mourning cloaks, especially where there are sap flows on tree trunks. Many brushfoots can be found just about anywhere there are open areas with flowers and caterpillar host plants.

The common ringlet prefers open grassy areas like fields or roadsides and may be elusive to find.

One species, the mourning cloak, is notable for overwintering as a butterfly here in the New England cold season. On warm winter days, you may see one flying in open, sunny woods. It normally does not visit flowers, but gets its nourishment from dung, rotting fruit and sap flows on trees.

Caterpillars of the brushfoots usually have spines, which, although menacing enough to the eye, are harmless if touched. A notable exception is the familiar monarch caterpillar which is spineless with a set of horns at both ends of the body. Some caterpillars, like those of the comma, American lady, Baltimore and red admiral, spend the daytime inside leaf shelters made by tying leaf edges or masses of leaves together. Knowing host plants is useful when looking for these caterpillars. If the shelter is opened slightly, you will find the caterpillar resting calmly inside.

Some members of the brush foots like the question mark and the comma butterflies have angled wings. Most are brightly colored and quite beautiful, like the common buckeye, which is a vagrant visitor here in Connecticut. Others have brown camouflage patterns on the undersides of the wings, like the question mark and the comma. When they rest on leaves or twigs with the wings folded upright, they appear to be dead leaves.

Colors and patterns on the wings can vary dramatically on brushfoots. Often the upper wing surfaces are more brilliantly colored than the undersides. Or they can be just as colorful when viewed either on the top or underside, but have different patterns. An example is the great spangled fritillary, which is orange and black on the upper wing surfaces, but the undersides are orange with brilliant white spots.

Several brushfoot butterflies are migratory, going south in the late summer and early fall, and then returning the next spring. Monarchs, painted and American ladies, and red admirals are some of the migratory species. They return north when wild mustards, crabapples, invasive honeysuckles and early native plants are starting to flower.

One brushfoot of special concern in Connecticut is the colorful Baltimore butterfly. Smaller than many other brushfoots, the Baltimore is striking as an adult, a caterpillar and a chrysalis. Caterpillars overwinter in large groups inside shelters they make by tying leaves together with silk. Look for these butterflies in large open fields that have water nearby.

As the winter comes to a close and the spring brings us warmer days and flowers, remember to look for the arrival of the migrating brushfoot butterflies. The first to arrive are usually the red admirals and American ladies and monarchs will follow later on in mid-to-late June. You may be able to sit awhile in the sun and have a red admiral land on you- a common, which is a happy occurrence in the life of a butterfly connoisseur.

We may be in the throes of winter but there is a place in New England where the most beautiful and delicate flowers bloom year-round. These flowers are presented in all their glory in displays that have recently been upgraded to enhance the viewing experience. These flowers and specimens will never wilt or fade, they are forever captured in a state of perfection. These are neither fresh, dried, preserved, nor photographed flowers. They are the Ware Collection of Blaschka Glass Models of Plants, the famous “Glass Flowers” of Harvard University.

I first saw the Glass Flowers several years ago when our daughter Hannah, then a student at MIT, suggested a visit to the nearby Harvard Museum of Natural History in Cambridge, Massachusetts. As with most natural history museums the collections ranged from wildlife specimens and fossils to minerals and gemstones. But it was the Glass Flowers exhibit that Hannah knew that I would enjoy most.

newgf-case_far_wall_0050_1_0

Although it is familiarly known as the Glass Flowers this exhibit actually represents over 4,000 models of 830 plant species and includes incredibly realistic and detailed models of enlarged flowers and anatomical sections of the floral and vegetative parts of the plants (clockwise from top left: Banana, Verbascum thapsus/Common mullein, and Gossypium herbaceum/Wild cotton).

Prior to 1886 the Harvard Botanical Museum, under the direction of George Lincoln Goodale, used pressed plant specimens, wax models, and papier-mache as samples for study. Pressed specimens are of limited teaching value as they are 2-dimensional, dried, and lacking in color, wax models and papier-maché were rough and didn’t stand up well. Around this time, Goodale saw some glass models of marine invertebrates in the Harvard Museum of Comparative Zoology that had been created by the father and son partners Leopold and Rudolf Blaschka from Hosterwitz near Dresden, Germany. He contacted Leopold Blaschka who then made and shipped a few botanical specimen samples which even though they were damaged in US Customs still showed the possibilities of further work.

There were other glass-blowers at the time and it was said that no-one could replicate the secret methods employed by the Blaschkas. The Boston Globe said that the glass flowers were “anatomically perfect and, given all the glass-workers who’ve tried and failed, unreproducible”. But in fact, there were no secret methods employed and their techniques were commonly known to other artisans. In addition to glass the Blaschkas used wire supports, glue, paint, and enamel in their work. Their method melted glass over a flame or torch which they controlled with foot-powered bellows in a technique known as lampworking. This differs from glassblowing which uses a furnace as the heat source. The molten glass was manipulated, pinched, and pulled with tools to achieve the desired forms. The finished specimens were occasionally formed from colored glass but were often hand-painted.

Leopold Blaschka credited their ability in this way, “get a good great-grandfather who loved glass; then he is to have a son with like tastes; he is to be your grandfather. He in turn will have a son who must, as your father, be passionately fond of glass. You, as his son, can then try your hand, and it is your own fault if you do not succeed. But, if you do not have such ancestors, it is not your fault. My grandfather was the most widely known glassworker in Bohemia.” Schultes, Richard Evans; Davis, William A.; Burger, Hillel (1982). The Glass Flowers at Harvard. New York: Dutton.

(at right, Caroline and Leopold Blaschka, seated, Rudolf Blaschka, standing)

 

The original 10-year contract between the Blaschkas and Harvard commissioned the work at a rate of 8,800 marks per year ($3,533 US dollars) or approximately $91,565 in 2017. The funding came from a former Radcliffe College botany student of Goodale’s, Mary Lee Ware and her mother, Elizabeth Cabot Ware, members of a wealthy Boston family. Additionally, all freight charges were covered by Harvard.

So, the artisans have been commissioned. Remember, the year is now 1890, film photography is in its infancy and it is about 100 years before the internet is available to the public. So how do two glassmakers in Germany research botanical specimens from all over the world? Well, some plants were sent from America and raised in the Blaschka’s garden. Other plants that were tropical or exotic were viewed in the royal gardens and greenhouses of the nearby Pillnitz Palace (below images). Rudolf Blaschka traveled to Jamaica and the United States in 1892 to make drawings and collect specimens. Leopold died in 1895 but Rudolf continued to work until his retirement in 1936. Rudolf had no children and had never taken on an apprentice so there was no one to take over from him ending a 400-year-old dynasty.

But the legacy of Leopold and Rudolf Blaschka lives on in over 10,000 glass models that are in museums the world over. Although the greater number of these are marine specimens it is the Glass Flowers that are most famed. The Glass Flowers encompass 164 families and 780 species in 850 full-time models. There are 4300 detailed models of individual floral and vegetative parts that capture every detail, right down to a grain of pollen as in the example of Lupinus mutabilis (Lupine) shown below.

There are models that show the fungal and bacterial diseases of fruits in the Rosaceae family that includes apples and pears (The Rotten Apples, shown below).

Others show insects in the act of pollination such as their depiction of a male fruit fly on an orchid, top image, or the bee on Scotch broom, below. Plants are exhibited from the simplest to the most advanced in the order of evolution.

This is not an exhibit that you would speed through. Each specimen is so enthralling that it is difficult to move on to the next one. The fact that every item there was created by only two men is mind-blowing and can be attested to by the tens of thousands of visitors each year. If you haven’t been to the exhibit I highly recommend it and if you have been in the past in would be worth going to see it in its restored glory. Visit the Harvard Museum of Natural History site for additional information and to view their videos of the Restoration and the Rotten Apples.

I bought some yellow fleshed beets at a nice farm stand in the fall. They looked good to me on the outside. Once I cooked and cut them open, though, this very dark (at least after cooking!) hollow center was revealed. It was present in all of the several beets in the bunch. The good news is that it could just be cut out and the beets were still delicious.

But what might have caused this symptom? There are a couple of possibilities and the cause was not determined. Those that come to mind include inconsistent water supply and boron deficiency. Sometimes when a crop is growing slowly due to limited rain or irrigation followed by a sudden plentiful supply of water, the growth rate can suddenly increase and result in this ‘hollow heart’ symptom or disorder. I know this happens in potato but I’m not sure whether it’s likely in beet. There’s a major difference between the two….potatoes, while they grow underground, are actually stem tissue. You can tell because they have buds, what we commonly call the eyes. Beets, on the other hand, are root tissue.

Boron is a micronutrient for plants and a deficiency has been associated with hollow sections of stems or roots in some crops. Beets are listed among those crops that have a high boron requirement relative to others. Factors that can influence the availability of boron to plants include soil pH, sandiness of the soil, and soil organic matter content. A consistent and adequate amount of water uptake by the plant is necessary to take in boron from the soil. This is influenced by transpiration, the loss of water from the leaves. Conditions that reduce transpiration, such as humid, cloudy or cool weather, can be related to deficiency. High pH (alkaline) reduces availability of boron. Sandy soils or those with low organic matter content are more prone to boron deficiency.

How could the cause in this case have been figured out? Soil and tissue analysis can be used to measure nutrient availability and content in the plant parts. Soil tests can check not only nutrient content but also organic matter levels. UConn’s soil and tissue analysis lab info can be found at www.soiltest.uconn.edu. If a boron deficiency is confirmed, soil can be amended using borax, boric acid or Solubor. Different vegetables have different boron requirements. Lists of those most likely to develop a deficiency can be found in this fact sheet from UMass.

Often times, the people, places and things that we encounter going about our daily lives are not given as much attention as might be merited. If they were gone though, they would likely be missed. New England in January without a new, pristine snow cover, can be drab and rather dismal, especially on cloudy days. Thankfully, the green goodness of eastern white pines is spread throughout our landscapes. On our walks, driving to the store or work, in our parks, along the highways and even in many backyards, eastern white pines (Pinus strobus) with that slight bluish cast to their needles adds a bit of greenery to an otherwise bland landscape.

Eastern white pine is a fast growing evergreen tree native from Canada down the east coast to Georgia and westward to the Great Lakes region. It is the only native pine in Connecticut that produces needles in bundles of 5. These are held together at the base by a deciduous sheath. New needles sprout forth each spring. Whereas deciduous trees lose their leaves each fall, the needles on an eastern white pine last for 2 years before abscising. We northerners tend to either leave pine needles in place in naturalized plantings, or rake them up if they fall upon the lawn. In the southeast, pine needles, aka pine straw, are sold as a mulch.

They do make a good mulch so if you happen to have a plentiful supply, consider using them in this manner. Often questions will arise about using pine needles as there is a false perception that pine trees somehow make our soils more acidic. In reality, eastern white pines have evolved to grow well in our native, typically acidic soils. Since our native soils are often nutrient poor, the trees will absorb as many nutrients in the needles as possible before letting them senesce so the dried, brown needles that fall from the tree are just slightly acidic which is a perfect pH for many of our garden plants. And, if your soil pH is a bit on the low side, just add some limestone.

When the early colonists first set foot in America, huge amounts of the northeastern and northcentral parts of this country where covered with old growth eastern white pine forests. The Native Americans used this tree for medicinal, food and utilitarian purposes. The needles were made into teas used for colds and other respiratory ailments. They are also high in antioxidants and vitamins A and C. There are recipes to make tea from fresh or dried needles online these days and prepared tea bags can be purchased as well. The inner bark or cambium was consumed as food by some tribes and the resin was used to waterproof buckets, baskets and boats.

A number of wildlife also depend on eastern white pine for part or more of their survival. Deer will occasionally graze on them during severe winters but I have found they typically prefer my yews and my one strategically placed (for visual impact) arborvitae. Black capped chickadees and pine warblers look for insects in the bark, branches and needles. The seeds are loved by mammals such as eastern chipmunks, white-footed mice, red backed voles, and grey, red and flying squirrels. A number of bird species also find them appetizing including red-breasted nuthatches, pine siskins, chipping sparrows, evening grosbeaks, grackles and crossbills. Porcupines may feed on the bark of eastern white pines as well as seek shelter in the evergreen trees.

Eastern white pines grow very fast, very large and very tall. These were all qualities appealing to the early colonists, their British rulers and future commercial venues. Eastern white pine was great for building and used in early colonial homes for floors, furniture and other purposes. It was easily cut and took paint readily and as such in high demand.

In the mid 1700s, the British Royal Navy needed tall, straight timbers for masts on its ships. These types of trees were in short supply in England as their navy continued its expansion so exceptional eastern white pine trees in the American colonies were marked for harvest and export to Britain. New Hampshire colonists, in particular, did not like this and cut down the marked trees for local timber use. This insurgence lead to the Pine Tree Riot in 1772. There was even a pine tree flag created in support of this rebellious group defending local natural resources from plundering by a higher order.

pine tree flag

Pine tree flag – Origin by E. Benjamin Andrews (1822-1917) – Taken from The Project Gutenberg EBook of History of the United States, Volume 2 (of 6), by E. Benjamin Andrews, c. 1894. From: https://en.wikipedia.org/wiki/Pine_Tree_Flag

Extensive logging by Americans from the 18th to 20th centuries lead to a reduction of about 99 percent of old growth eastern white pine forests from the east to the Midwest. While these majestic trees can live 4 or 5 hundred years, only about 1 % of old growth forests remain. Most of today’s stands sprang up after their parents were cut down and former productive tree lots abandoned. Although not as tall as their ancestors yet, Connecticut has 2 co-champion notable eastern white pine trees, both around 130 feet high. They are located in Thomaston and in Morris.

Some decimated areas were replanted with white pines from Europe. It may seem odd for native tree seedlings to be grown in Europe and shipped here but the Europeans had previously recognized the foolhardiness of the overharvesting of timber and had established nurseries to efficiently propagate various species including pines. Unfortunately, shipments that arrived in 1898 and 1910 were infected with a disease called white pine blister rust. This is a curious disease that has two hosts – the eastern white pine and ribes species including currants and gooseberries. It originated in Asia. Young pines were particularly susceptible and in some areas up to 80% of trees were killed. Control measures led to ribes eradication efforts. Some states passed laws prohibiting the cultivation of currants and gooseberries. This disease still lingers but perhaps because of developed resistance, fewer gooseberry and currant plants and climate conditions, the incidence of white pine blister rust is relatively low in Connecticut.

Fortunately, eastern white pines are resilient. Despite the fact that the earlier settlers cut down swaths of old growth forests on their move westward and the destruction that was wrought by the white pine blister rust during the early 20th century, eastern white pines still rule. So admire them on your drive to work, examine them more closely as you walk the dog, and plant one in your yard if you don’t already have this tree growing. This plant is a necessity to our native wildlife and it is a notable part of the New England countryside.

snow and tree

As I sit here inside, watching the cold wind blow and snow pile up outside the warmth and safety of my little writing spot, I wonder just how all those living beings outside are surviving. Trees are swaying in the wind, and birds trying to visit the feeder are forced to alter flight plans while sporting ruffled feathers. The only animals I see are hunkered down squirrels. And just where did the insects go?

A little research tells me all of the annual plants are dead. They completed their life cycle in one year going from germinating a seed to producing seeds which are waiting winter out to make new plants in the spring. In my vegetable garden I call them volunteers. You know those tomato seeds that germinate from last year’s rotted tomato fruit that dropped to the ground and its seed volunteered to grow where I didn’t put this year’s crop. The seed survived through the winter, not the plant. Annual weeds drop seed in this manner, too.

IMG_0877default

Perennial plants are a different story, although their seeds can do the same overwintering as annuals, the existing plant can live through the winter to grow another year, hopefully for many years more. Trees and shrubs are woody perennials that have woody above ground structures and roots that overwinter. Herbaceous perennials overwinter their roots and crowns only. The above ground portion of the plant dies back, but the crown and roots are alive at level or below ground. Perennial plants go dormant, living off of stored food until warmer weather returns. Storage organs of plants are the thick roots, rhizomes and bulbs. Just how they prepare themselves to make it through the winter happens at the cellular level long before freezing temperatures begin.

Plants are triggered by the amount of light and the amount of dark they experience, and lower night temperatures signal to get ready for winter rest and dormancy. Different species have varying light and temperature levels signals. Deciduous trees and shrubs must begin the process of losing their leaves by first stopping the production of their food. We notice it in slower growth and in the leaf color. The leaves are the food factory of the plant where photosynthesis happens. Carbohydrates are made then stored in roots and woody parts of the tree or shrub. Lots of light and water results in good growth and food storage, but when light amount lessens, leaves slow down production. Chlorophyll is also produced during photosynthesis, giving the leaf a green color. Once the leaves stop working, no more chlorophyll is produced and the other plant pigments of red and yellow are exposed now that there is no green chlorophyll to cover them. This is when we see beautiful fall foliage. The next change happens in a specialized layer of cells at the point where the leaf stem (petiole), attaches to the twig called the abscission layer. These cells enlarge and harden to choke off water flow to the leaves and the leaf slowly dies and falls off.

tree in fall

The next cellular change is called cold hardening. It happens within the vascular system containing the plant juices and water. If water inside the cells freeze, it will rupture the cells, permanently damaging the plant. The cold hardening process increases the sugar content of the water, and makes other protective chemicals, lowering the freezing level of the plant liquid. Basically the plant makes its own antifreeze. Cell walls are also changed to allow water leakage into spaces just outside the cell so if crystals do form, damage will be avoided. The acclimation of all these changes makes the plant able to tolerate below freezing temperatures. Fall pruning or fertilizing with nitrogen during August and September stimulates new growth interrupting the cold hardening process.

Evergreen trees and shrubs have thick leaves with waxy coatings to prevent moisture loss. Some broadleaved evergreens have gas exchange openings called stomata on the underside of the leaf. In very cold weather the leaves will curl as the stomata close to prevent moisture loss. Rhododendrons are a good example. Evergreen plants will continue to photosynthesize as long as there is moisture available, but much more slowly during the winter.

Animals and insect have the ability to move, unlike plants. They can migrate, hibernate or adapt to winter’s cold. Certain birds migrate to warmer areas and better food sources. Hummingbirds, osprey, wood ducks and song birds fly south, and some birds from far north in Canada come south to spend the winter here. Juncos, snowy owls and bald eagles summer at a higher latitude and spend the winter nearer to us. They go where they can find food.

Some animals go into a winter dormancy or hibernation. This phase consists of greatly reduced activity, sleep or rest, and lower body temperatures while their bodies are sustained from stored fat. Bears, woodchucks, skunks, bats, snakes and turtles all have true hibernation, not waking until light levels increase and food sources begin to be available again. Bears and bats find caves, woodchucks, and skunks dig tunnels, snakes and some turtles burrow into soil and leaf litter, all in protected sites.

woodchuck at entrance to tunnel

Other animals such as chipmunks have underground burrows lined with stored nuts and other food. Beavers do the same in lodges they build just above water, and line with stored logs to feed on during the winter. They sleep for long periods, only waking to eat and if maybe take a short walk above ground before returning to their den. Fur bearing animals will grow a thicker winter coat to help keep them warm, and may be a whiter color to provide camouflage in the snow.

Voles are active all through the year. In winter, they will tunnel through the snow, just on top of the ground looking for plants material to eat. They will strip the bark off of young trees and eat the roots. Voles store seeds and other plant matter in underground chambers. Mice are active and breed year round, living in any protected nook or cranny they can find, including our homes. They store food in hidden spots away from human and predator activity. Check for mice tracks around your foundation after a freshly fallen snow to see if mice are using your house for their winter quarters. Moles are active deep underground, below the frost line, in an elaborate array of tunnels. They feed on soil dwelling insects throughout the winter. I guess you could say they go ‘south’ in the soil profile during cold weather of winter.

Squirrels do not migrate nor hibernate, they adapt. They are active all winter, raiding bird feeders, and feeding on stored nuts. They grow a thicker coat of fur and fat for winter. Squirrels make great nests high in trees, well insulted with leaves. Several grey squirrels will share a nest to keep warm. They are often too quick to get a close up photo!

Insects as a group are very large and diverse. Some migrate in their adult stage such as monarch butterflies and some species of dragonflies. Others overwinter in pupal stages like the chrysalis’ of spice bush swallowtails or cocoons of Cecropia moths.  Others adult and immature insects, depending on species, enter a state of diapause, similar to hibernation in animals, to overwinter during the winter. Diapause is a dormant semi-frozen state for some insects.  And like plants, changes at the cellular level occur, too. These insects produce an alcohol-like chemical and added sugars to the moisture in their bodies to prevent freezing, just like vodka will not freeze when placed in our home freezers. Insects will first seek out a protected place in the soil, leaf litter or under lose tree bark or rotten logs.

The brown and orange woolly bear caterpillar burrows into the forest floor to spend the winter as in its larval stage. In spring it will come out of its dormancy to pupate, later becoming an Isabella tiger moth.

Other insects lay eggs singly or in mass groupings, which are equipped to live through the winter and hatch when conditions are good again. Gypsy moths spend the winter as egg masses, tolerating down to -20 F temperatures. Crickets are another insect group which lays eggs in the fall on the ground that will provide a new generation of night songs for us to enjoy the next summer.

The one thing I like about January is that at least the days are getting a teeny bit longer. We still have the cold weather and probably a bunch of snows will fall, but the nights are shorter and I am fooled into thinking spring will soon be here. While I like to escape into the wilds in the warmer, more colorful months, it can be a more difficult enterprise now. Snows may not allow an easy walk in the woods, but the roads are clear, and they will have to do as a means of checking out the January happenings outdoors.

Although cold, the air is nice and clean (it seems!) and crisp, providing a refreshing change to an extended existence in an indoor environment. And there is still much to see in the winter. Bird species may not be as abundant, but the ones that are still here provide a nicer experience for me than watching fish in a tank would.

Pileated woodpeckers may be elusive, but they are quite vocal, and so they often give away their location as they gad about in the woods. Water birds are still around- a kingfisher is still finding stuff to eat in areas of open water- and mallards and Canada geese are, too. Coots may be seen in open water near the shore, and merganzers and ruddy ducks can be found in small or large flocks in the coastal areas. And Cooper’s hawks, as well as sharp-shinned hawks, small accipiters that prey on birds, can be seen buzzing bird feeders for easy pickings on a winter’s day.

In my town, there is a large population of black vultures now, which is a remarkable development as just a few years ago avid birders would ‘flock’ to an area where a black vultures was reported to be. During the 1990’s, black vultures were considered very rare visitors to Connecticut, but in the last few years, they are definitely staying year- round and breeding here. You can tell black vultures from turkey vultures in flight by the white bands on wing tips, versus the half silver wing undersides of the turkey vultures.  Up close, the gray faces of black vultures are readily distinguishable from the bald, red faces of turkey vultures. Black vultures will often congregate on chimneys on cold days.

We had very cold weather the last two weeks- down in single digits on a few mornings and not much above the teens the rest of the time. Today, it is raining and fifty two degrees. If warm conditions keep up for a few days, fireflies may come out from their winter hiding spots in bark crevices, Look for them on sunny sides of trees in wooded areas. They will not fly, too logy for that, and will return to their resting places as the weather gets cold again.

When we have snow cover, that presents an opportunity to check out animal tracks in the snow. Deer tracks require no great hunter-like skills to figure out, but others may be tricky. I get a kick out of mouse tracks- don’t’ know why- maybe because they are one of the few animals that leave a tail print between the footprints.

Two of my favorite native plants that give interest to the monotone winter landscape are the redosier dogwood, Cornus sericea and winterberry, Ilex veticillata. Both plants offer a splash or red to a snowy landscape, and winterberries offer a food source for many birds and some small animals. Winterberry is found in the wild along edges of woods and swamps, and redosier also prefers similar areas in the wild.

Even though it is not a native plant, I do love the Norway spruces when they have established mature stands. Red squirrels, at least, also appreciate the seeds that are one of their important food sources in the winter. You may come across piles of the spruce cone scales where the little pissant red squirrels take off the scales to access the seeds inside.

Indoors, though, it is warm, as well- lit as you may desire, and a better relaxing environment in January. Until the warm weather comes, perhaps an orchid in flower may providing a charming blush of living color, while we wait for nature to do the same.

   “The grass on the rock, the flower of the heath, the thistle with its beard are the chief adornments of his landscape.” Ossian.

Well, here we are. 2017 has come to an end and 2018 lays before us. We are at the darkest time of the year as the winter solstice, which occurred on December 21st, brought us only 9 hours and 8 minutes of daylight on that day. That is 6 hours and 5 minutes less daylight than on June 21st! Its no wonder that this time of year is referred to as ‘hibernal’, a time when the deciduous trees are bare, the dropped leaves begin to decay, and birds and wildlife have settled into their winter homes and habits.

In Connecticut winter-time means that most plants have either died back or gone dormant. The evergreens hold onto their leaves and needles but they are not actively growing. Some of the more common evergreen landscaping plants for zone 6 such as the (clockwise from the top left) the rhododendron (Rhododendron sp.), the Eastern white pine (Pinus strobus), the mugo pine (Pinus mugo), and the white spruce (Picea glauca) add so much to the barren winter landscape.

The non-evergreen perennials can also be of interest during this time. From the top left clockwise, the American pussy willow (Salix discolor), the stonecrop (Sedum sp.), and the hydrangea (Hydrangea paniculata) all add some textual variety to the landscape.

Their monotone appearance doesn’t really catch the eye like the very appropriately named winterberry (Ilex verticillata) does. One of the deciduous hollies, winterberry looks especially outstanding after a snowfall. As with most hollies the winterberry is dieocious and requires a male and a female plant to produce these beautiful red drupes which will remain on the plant through a good part of the winter to the benefit of small mammals and more than 40 species of birds.

But I would like to talk about an evergreen shrub that holds not only its leaves but its flowers all winter. Known as spring or winter heath (commonly but incorrectly called heather) Erica carnea has the most delicate, bell-shaped pink flowers and whorled, needle-like leaves that are barely ½” long. The family Ericaceae also includes the true heathers that were once included in the genus Erica but are now in the genus now called Calluna. Calluna heathers are called summer or autumn heathers and can be identified by their smaller, scale-like leaves which are in opposite pairs and their flowers which emerge in late summer. It is the heather Calluna vulgaris that evokes images of wide expanses of Scottish highland moors that appear to be covered in a pink mist.

It was the winter heath, Erica carnea, that stood out as I walked through our yard on a recent sunny but bitterly cold day. Its tiny pink flowers don’t seem capable of withstanding the arctic temperatures of the past week yet there they are.

The compact, or dwarf, size of most heath helps to limit the amount of air circulation through the plant and it creates its own microclimate whereby the plant is not as vulnerable to the cold as a taller, more openly branched plant. Its low growth habit does expose it to the possibility of frost when very cold air settles near the ground but it’s likely that in Connecticut a cover of snow may insulate it.

Early spring and early fall are the best times to plant, feed, or prune heath. When planting in full sun or slight shade in the early spring or fall do not allow these shallow rooted new plantings to dry out before they can establish themselves. Some gardeners amend the soil with peat moss, which can hold more than 20 times its dry weight in water in its cells, to help retain moisture. If you do add peat moss your heath plantings will receive an added benefit as the moss takes up calcium and magnesium from the surrounding soil and releases hydrogen. This action, called cation exchange, acidifies the soil. Heather prefers acidic soil which means that they are well suited to Connecticut. Plant them in area that will not be affected when you lime your lawn. Give them a dose of Holly-tone once a year when fertilizing other acid-loving plants such as rhododendron, azalea, or holly making sure that it doesn’t adhere to the foliage and reaches the drip line of the plant. As with any fertilizer it should be watered in.

Spring is also good time to do any pruning of heath before the plant sets its flower buds or has new growth. Prune just to control any unwanted spreading and avoid pruning in the late fall as open cuts can collect water that will expand during a freeze and cause the stems to split. True heather (Calluna sp.) should be pruned annually in the spring as the flower buds do not set on old wood and the plants will become leggy and unattractive. Prune C. vulgaris at the base of old flowers.

Other than needing occasional pruning heath and heather are very low-maintenance plants with few issues. You may find that deer or rabbits will feed on it as will the larvae of the Lepidopteran order which includes butterflies and moths or moths in the Coleophora genus. All in all, these plants are a wonderful addition to any yard or landscape as they unobtrusively add a swath of pink flowers and deep green foliage year-round. Perhaps 2018 is the year to add some year-round color to your landscape!
