Perennials


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.

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.

“By all these lovely tokens
September days are here,
With summer’s best of weather
And autumn’s best of cheer.”
–   Helen Hunt Jackson, September, 1830-1885

September brings a wealth of inspiration to the senses. Leaves of Virginia creeper are red already, there is the intoxicating scent of wild grapes in the pre-dawn foggy mornings, asters and goldenrods bring colorful splashes to the landscape and sunsets may fill the cooling sky with brilliant deep reds and oranges. Tree Hydrangeas, Hydrangea paniculata, had a great year, and many still have panicles of colorful flower heads. While many plants and insects are winding down to an early retirement, there is still a lot going on in the great outdoors.

It may be the time of year for oddities, now and then. For instance, there is a horse chestnut outside our office on the Storrs campus that has several flowers in full bloom this week. While many shrubs and fruit trees, like cherries and azaleas, may have a secondary bloom in the fall after rains, cool weather with a late autumn warm spell following, a chestnut blooming at this time of year is a more remarkable event. A bumblebee spent time visiting the flowers, so a second round of pollen and nectar is a bonus in that quarter.

Red-headed crickets are a first for my gardens this September. These small crickets have a distinctive red head and thorax, iridescent black wings, and yellow legs.  At first glance, they really do not appear to be crickets because of how they move around vegetation. They also have large palps with a paddle-like end that they wave around almost constantly, giving the appearance of mini George Foremans sparring in the air before a fight. Found mostly only three feet above the ground, they have a loud trill and are usually more common south and west of Connecticut.

While visiting Kent Falls recently, I came upon a few small clumps of American spikenard. Aralia racemose, loaded with berries. Highly medicinal, this native plant is found in moist woodland areas such as along the waterfall trail at Kent Falls. Roots are sometimes used as a substitute for sarsaparilla, another Connecticut wildflower.

Many migrating butterflies like monarchs and American Ladies are on the move now and may be found on late season flowers like butterfly bush, zinnias, Tithonia, Lantana, cohosh, goldenrod, asters and many other flowers. In annual plantings where I work, honey bees are especially abundant on Salvia guaranitica  ‘ Black and Blue ’  right now.  And while many butterflies and bees can be found on various butterfly bush cultivars, the hands on favorite seems to be the cultivar ” Miss Molly” which has deep red/pink, richly scented flowers that attract hummingbirds, flower beetles, fly pollinators, people and bees galore. This is a great addition to a pollinator or butterfly garden. Other late season bloomers for our native insects and butterflies are black cohosh and Eupatorium  rugosum, (chocolate Joe-Pye weed), as well as asters and goldenrods.

Snapping turtles are hatching now.  The other day while mowing fairways, I spotted long dew tracks and there at the end were two little snapper hatchlings. Very soft upon hatching, they are often heron chow, and these little turtles will travel long distances to find a good habitat.

Every day at my house, we engage in a “Where is Waldo?” type hunt in the backyard gardens. What we are looking for are the tiny gray tree frogs that are hanging out on certain plants during the day. Snapping up any insects that get too close, these guys are a lot of fun to watch and look for. Most of ones we are finding are green, and are slightly larger than a thumbnail right now.  It gives us all some free entertainment before the leaves fall and we move on to- raking leaves…

Katydids, crickets and sometimes tree frogs are making a racket at night. Although really not unpleasant, to me, they are loud. But more enjoyable to listen to than the neighbor’s barking dog…I found a katydid eating a hyssop flower recently, but who cares about that this late in the year?

Bees are having their last hurrah now as the blooming season winds down. While native goldenrods and asters are important food sources of food for late season bees and wasps, there are many garden plants that are important nectar and pollen sources as well. In my own garden, I have two hyssops- anise and blue giant hyssop. There were bumblebees and honeybees that went on both, but there were small bees that preferred only the anise hyssop. These bees were very noisy, and hovered near flowers before landing, behaving like hover flies. Most likely these bees were in the Megachilid genera- the leaf-cutting bees. Abdominal hairs collect the pollen in these species and may take on the brilliant colors of pollen from the flowers they visit.

As the season winds down, there are still some caterpillars to be found, like the beloved wooly bears and other tiger moth cats like the yellow bear. A spotted Apotelodes was a good find. A robust, densely hairy caterpillar, this large fellow is notable for three sets of long hairs called “pencils” along the dorsum, and for its equally conspicuous red feet, making it look like it is wearing five pairs of little red shoes.

And just for fun, next year consider planting a candy corn vine, Manettia inflate, on a small trellis.  An annual vine, flowers last well into the fall before the first killing frost. This South American native has tubular flowers that resemble candy corn, and they are a favorite of the hummingbirds (and myself!) in my backyard.

Germander

Germander Plant, CQuish photo

Germander is an unusual perennial herb which makes a great edge of the border plant. Its Latin name is Teucrium chamaedrys. Germander takes well to shearing to form a garden border or knot garden, making it a good alternative to boxwood plants. Size of each plant will be about 10 inches tall with equal spread. It has also been used as a bonsai plant with great results.

Germander is native to Europe, Syria and the Greek Islands. It likes a pH of 6.3 and well-drained soil. Plant will produce pink blooms sporadically from mid-summer through the fall. Leaves have a strong unusual scent when crushed, and have traditional been harvested for medicinal properties to treat a variety of ailments in times before modern medicine. Although some folks still practice herbal remedies, we cannot recommend them in this forum as we are not doctors. Cut branches make a lovely wreath for decoration and freshen the air inside.

Leaves are dark green, tiny and have serrated edges giving a fine overall texture to the plant. Germander is in the mint family, but behaves well in the garden, not spreading much. It also is not liked by deer due to its scent, and insects and diseases rarely attack adding to its attributes. Prune before new growth starts in the spring.

IMG_20170702_114322695One of the best things about summer in Connecticut is the easy drive to the Connecticut shore as almost any point in Connecticut is no more than a 1 ½ hour drive to the Long Island Sound. Although Connecticut is the third smallest state area-wise (5543² miles) we are ranked either 17th or 20th in total ocean coastline. The 20th ranking is from the National Oceanic and Atmospheric Administration (NOAA) which includes tidal inlets and the Great Lakes in its calculations. Our 17th place ranking says that we have 96 miles of coastline while the 20th place gives us a grand total of 618 miles. In fact, if every citizen of Connecticut stood very close (and held our babies and toddlers) we could all stand along that 618-mile coastline! I must admit, as we walked along Sound View Beach over the 4th of July weekend it felt as if that scenario was taking place.

But walking a little further away from the sea of humanity is when the real appeal of the Connecticut shore happens for me. The diversity of the plants and vegetation that can be encountered never ceases to amaze me. Even though hydrangeas grow all over Connecticut, including in our yard in Enfield, they never seem as deeply blue as they do when there is a touch of salt in the air…

The Connecticut coastal region has a longer frost-free season than most of the state of Connecticut, 15-35 days longer depending on where you live. I would love an extra 35 days of growing time for my gardens but I don’t know if I would be willing to exchange those extra days just to worry about the salinity tolerance of my plants, sandy soils that may drain too quickly, or high winds. Those are all a part of the ecoregion along the Connecticut shore and each of those factors play a part in selecting plants for landscaping in that area.

IMG_20170712_084312269_HDR

Salt can affect and potentially kill shoreline plants in two ways; either through salt spray that can damage leaves and plant tissues or through groundwater where salt water is brought in on daily tides. Where the groundwater is highly concentrated with salt water plant tissues can be damaged as with salt spray but additionally they will suffer with water uptake issues. When the concentrations of salt in the soil surrounding the roots of a plant become too high the plant may be forced to accumulate salts in its root cells to compensate for the higher levels outside. Expending energy to facilitate these functions means less energy will be directed toward the growth and vigor of the plant, sometimes causing the roots to go dormant, and resulting in a poor or stunted appearance.

Have you ever noticed how plantings along the shore seem to almost hug the ground? When salt is dissolved in water it separates into equal ratios of its two ions: sodium and chloride. It is the build-up of chloride ions in plant tissues such as the stems and leaves that will present as browned, bronzed, or ‘scorched’, leaf edges.

scorched

Even the slope of the land or whether there is a sea wall present will influence the amount of salt damage that can occur. Within the same property or area several different salinity levels may be present as plants that are on the lower end of a slope may receive twice-daily infiltrations of seawater at high tide. And an area that slopes up will be more affected by salt spray. In fact, unlike the effect of elevated levels of salt in groundwater which tend to be localized, salt spray can reach plants several miles inland.

Fortunately, many species of plants that are native to Connecticut have developed the ability to thrive in these conditions and are categorized as highly salt tolerant, moderately tolerant, and least tolerant. Using plants that are highly tolerant as a buffer to shield less tolerant plants from salt spray, winds, or that simply increase the distance from areas of salty groundwater is a good option. The Connecticut Coastal Planting Guide from Connecticut Sea Grant/UConn has a great listing of trees, shrubs, herbaceous perennials, and groundcovers and their salt tolerance levels. Our recent trip to the shore showed some wonderful examples.

Like many landscaped yards in Connecticut our property has boxwood adorning our front yard, planted more than 30 years ago. This shrub is usually a minimal maintenance woody ornamental plant. It requires a bit of shaping once a season even though its slow growth habit doesn’t send out the random foot-long shoots that its neighboring Japanese maple does. In fact, the amount that is trimmed off is more like a ‘shaving’ of its foliage and the easiest way to collect the clippings is to place a tarp beneath the shrub (the tiny pieces of leaf are almost impossible to rake it up). We tend to do the shaping of the shrubs in the landscape somewhere near the end of June and beginning of July. I remember one year (and I’m sure that my daughter will never forget) trimming them on a hot humid day where we ended up wearing bits of foliage that stuck to our damp skin!

Over Memorial Day weekend this year as I walked past the boxwood that borders our driveway I was surprised to see it covered in a white fuzz. I stopped in my tracks for a closer look. Up and down the stems and in the leaf axils was a fluffy white coating that dispersed like a powder into the breeze when I touched the shrub.

IMG_20170530_074456085

Using a macro lens, I took successively closer images until what looked like just white fuzz became individual clumps and then minute insects. These are the nymphs of the boxwood psyllid and the white fuzz was waxy strands of their crystallized honeydew secretions that is also called ‘lerp’. Yes, that is a real word. Boxwood psyllid (Psylla buxi) are in the family Homoptera, a suborder that also includes aphids, scale insects, cicadas, and leafhoppers.

The tiny orange eggs of the boxwood psyllid overwinter in the bud scales of the boxwood and will hatch when the temperature reaches 80 degree days, around the same time that the buds open. Degree days are an accumulative measurement that allow the prediction of insect appearances and plant blooming. For more info on degree days, visit the Cornell University site: Network for Environment and Weather Applications.

Enfield, CT reached 80 degree days on May 18th this year and between then and mid-June when we accumulate 300 degree days the psyllid nymphs will go through 5 instar (nymph) stages. They mature into winged adults as they finish their incomplete metamorphosis. It was a bit slower this year due to the cooler temperatures. The adults will mate and lay their eggs under the bud scales, there is only one generation a year.

Most of the damage from the boxwood psyllid is in the leaf cupping that happens as the larvae feed. They have sucking mouthparts and the leaves curl around the nymphs as they feed, a rather tell-tale sign of their presence. The psyllid doesn’t do any substantial damage.

IMG_20170530_074410382

Meanwhile, another pest also made its appearance. A beautiful Goldflame honeysuckle, Lonicera x heckrottii that adorns our deck was getting its yearly aphid visit.

IMG_20150609_114321860

As a relative of the boxwood psyllid the feeding damage of this aphid (Hyadaphis tataricae) is very similar. They love the flower buds and can feed inside the bud before you can even know that they are there. Aphid damage will stunt the growth of the flower buds and prevent the honeysuckle flowers from blooming.

And that would keep us from one of the pleasures of outdoor dining on a summer evening: watching the hummingbirds visit the showy pink and yellow tubular flowers as they search for nectar. The hummingbirds dart in and out so quickly but they occasionally stop for a brief respite, barely bending the vining stem as they weigh so little, often less than 1/10th of an ounce.

Bees and other pollinators such as the Eastern Tiger Swallowtail (Papilio glaucus) also spend lots of time going from flower to flower on the honeysuckle. It’s important to keep these visitors in mind when dealing with pests such as the aphids. A systemic insecticide should never be used during the period when a plant is flowering. These pesticides will target all insects that feed on the plant’s sap, drink the nectar, or gather the pollen regardless of whether they are beneficial or not.

2012-07-26_13-27-04_844

A strong spray of water may dislodge aphids and psyllids or an insecticidal soap may be used. An insecticidal soap works as a contact pesticide and as such there is no residual insecticidal activity once the solution has dried. It must sprayed directly on the soft-bodied insects that it effectively controls. It also degrades quickly and will wash off leaf surfaces so that it won’t affect non-target insects, especially pollinators, or the lady beetles that consume the aphids in large quantities.

IMG_20170530_062842848

If you see (or have seen) psyllids or aphids you may want to do as I do and make a note of it in your calendar or your garden journal so that you can keep an eye out for them next year. Knowing when the aphids may show up on the honeysuckle gives me a bit of an edge in controlling them and allows the most blooms to come to fruition much to the enjoyment of humans, animals, and insects alike!

“Clouds are not spheres, mountains are not cones, coastlines are not circles, and bark is not smooth, nor does lightning travel in a straight line.”

– Benoit Mandelbrot, introduction to The Fractal Geometry of Nature

At this time of year many of the trees and shrubs in our landscapes are mere skeletons of their summer glory. Their beautiful canopies of leaves have been shed and they provide little visual interest. Unless you look a bit closer…

maple-tree

This is actually a great time to observe the branching patterns of deciduous trees. A closer look reveals that they are eerily similar to our own vascular and respiratory systems. As each system goes from the main trunk to the larger limbs to the smaller branches and then the twigs we see the same fractal branching that occurs in the network of blood vessels in our lungs. How incredible that such like systems are actually performing a reverse process. Trees are taking in our exhaled carbon dioxide and releasing oxygen (O2) into the atmosphere.  In turn, we inhale that O2 rich air into our lungs where it travels through the increasingly smaller vessels until it reaches the capillaries where it passes through into our bloodstream. As the oxygen-rich blood travels through our body our cells use the oxygen and release CO2 back into the bloodstream where it travels back to our lungs before releasing CO2 as we exhale.

2012-11-23_07-39-50_640

The important thing to remember is that for both of these systems to work well they need to cover a large surface area and fractal branching is the most efficient way for that happen. Fractal branching is a pattern that repeats itself in either larger or smaller scales, each step looking like a copy of the same overall shape. These patterns are called self-similar and are found in many areas in nature from trees to rivers and many more. Ferns are a great example of a self-similar fractal as each pinnate leaf is a miniature version of the larger frond that it branches off from although natural branching fractals do not go on infinitely as mathematical fractals can. Remember the Fibonacci Sequence from your high school math class?

japanese-painted-fern

Most of the fractals that we are familiar with and see on a regular basis fall into the category known as spiral fractals. Spiral fractals are responsible for some of the most beautiful forms that can be found in nature. Many galaxies are spiral fractals. The marine animal known as the Nautilus is perhaps one of the most well-known examples of the spiral fractal. But there are also so many spiral fractals that we encounter in the plant kingdom on a daily basis.

Ferns exhibit fractal properties in two ways. The uncurling of a new fiddlehead in the spring is a lovely example of a spiral fractal while a mature Japanese Painted fern (Athyrium niponicumn) pictured above shows the self-similar pattern of a branching fractal.

The Monkey Puzzle tree (Araucaria araucana)  has a most interesting growth pattern with each branch a continuing spiral of tough, scale-like leaves. Although native to Chile and Argentina, these images are of a specimen that is located on the Long Island campus of Hofstra University.

Closer to home are some plants that are in many of our gardens during the summer season. The compact spirals of Stonecrop, also known as Sedum, help to form the tight clusters of thick leaves that give it its distinguishing look. I always love the way that dew or rain collect in the in little cups that are formed.

Sunflowers (Helianthus annuus), Gerbera (Gerbera) daisies, and Coneflowers (Echinacea purpurea) show their spirals on a grand scale.

Decorative cabbage and kale (Brassica oleracea) are seasonal plants that bring their cold-resistant beauty to our fall landscaping and thus complete a full year of natural fractals that can be found all around us .

What’s a butterfly garden without butterflies?  Roy Rogers

tiger-swallowtail-2011-butterfly-bush

Tiger swallowtail visits a butterfly bush

 

Planting a butterfly garden is a hopeful enterprise which often has its rewards in the future and not in the same year of the planting. Typically, a couple of years is needed to provide abundant blooms and the subsequent attracting of butterflies. In my experience, the best butterfly gardens are those that include, as much as possible, the host plants that visiting butterflies will use for laying eggs for their caterpillars. Try planting a few blueberry bushes as several hairstreak butterflies us this as a host plant.

striped-hairstreak-on-milkweed-belding-6-30-15-2

When butterflies start to visit the garden, try to identify them and see if they may be laying eggs on already existing plants (like oaks and cherry, for instance, if tiger swallowtails are present). Having nectar sources nearby  the host plants for the caterpillars is a strong factor in what attracts butterflies to an area. So I say, if you plant it, they will come. Maybe. Sometime. They have to find it, so it can take time. If they are already passing through and laying eggs on suitable host plants, then nectar will keep their offspring coming back  to do the same.

I have planted a native willow for Mourning Cloaks that come through the property every year. A sassafras that appeared several years ago has now become a regular host plant for the spicebush swallowtails that visit the garden for nectar. When you see any butterflies, egg laying should shortly follow, if it has not already taken place. This is why host plants in the vicinity of nectar sources is so important when planning a butterfly garden.A lone tiger swallowtail visited my garden late this spring and three weeks later I found its tiny caterpillar on a small black cherry sapling I had transplanted earlier that spring. It was barely in the ground and already had become a host plant.

Three of the best butterfly gardens I have been to this year are the one at the Tolland County Agricultural Center in Vernon, the Cohen-Woodlands pollinator- butterfly garden in Colchester, and the Fletcher Library Garden in Hampton. The one thing all these gardens have in common is a good selection of three season nectar sources and nearby host plants. Four monarch caterpillars were on the butterfly weed in the Fletcher Library just two weeks ago, and one was on milkweed in the Cohen garden on September 5th. That is great news for the Monarchs which have suffered from devastating population declines in recent years.

Plant parsley, fennel or dill if black swallowtails visit a garden. Small cherry and spicebush attract tiger swallowtails and spicebush swallowtails, respectively. Viceroys will lay eggs on willow and poplar and red- spotted purples lay eggs on cherry. Skippers for the most part prefer grasses for their larva, but the silver- spotted skipper, a frequent visitor to any garden, likes legumes. Pearl crescents like asters, and these flowers are visited by many migrating butterflies as most other nectar sources are going by in late summer.

p1130405

A must plant for pollinators, butterflies and hummingbirds is Caryoptersis, also known as bluebeard. This perennial blooms from late- summer until fall. Lantana is a terrific annual for all butterflies, providing blooms until frost. Combined with asters, these plants are ideal nectar sources for fall migrators. Goldenrods, spotted Joe-pye, liatris, zinnias, obedient plant, alliums, butterfly bush, milkweeds, obedient plant and veronicas are also good selections for butterfly gardens. And there are so many more.

Annuals, perennials, trees and shrubs should all be under consideration when deciding what to plant for butterflies. My garden has been redesigned for birds, butterflies, pollinators and, just a little bit, for me. Although, I guess, it really is mostly for me because of the enjoyment I get watching these little visitors getting some use from the plants that were selected with them in mind in the first place. Of course, woodchucks were not in the equation (as squirrels were not either when putting out the BIRD feeder) …
