Environment


With the encroaching winter storm and dropping temperatures, I thought it would be appropriate to talk about a very interesting and unique soil order, the Gelisol. Soils are dynamic systems that are essential to life as we know it, and are nonrenewable resource that vary in physical and chemical composition throughout the world. Parent material (underlying bedrock, glacial deposits, wind-blown sediment, etc…), climate, topography, biological activity/factors, and time are the 5 soil forming factors. Different places on the planet will produce a wide variety of variations of these 5 factors. To help understand and classify soils, 12 different orders were formed. The 12 different Soil Taxonomy Orders are: Alfisols, Andisols, Aridisols, Entisols, Gelisols, Histosols, Inceptisols, Mollisols, Oxisols, Spodosols, Ultisols, and Vertisols. Each order has unique properties that are a result of 5 soil-forming factors.

Gelisols are, in my opinion, the most interesting and important soil orders. The Soil Science Society of American defines Gelisols as soils that are “permanently” frozen containing permafrost within 100 centimeters of the soil surface, and/or gelic materials within 100 centimeters and permafrost within 200 centimeters of the soil surface. Permafrost is soil and rock that remains below 0 degrees Celsius for a minimum of 2 years; and “gelic materials” are soil components that show evidence of cryoturbation, or frost churning, a mechanism unique to gelisols. Cryoturbation is the irregular breaking and mixing of soil horizons (think different segmented layers of soil) via the movement of water caused by seasonal melts and thaws. To clarify, just because your front yard is frozen for a few months in the winter is not enough to classify the soil within as a gelisol.

Figure 2: A Gelisol (SSSA https://www.soils.org/discover-soils/soil-basics/soil-types/gelisols)

According to the United States Geological Survey, around 9% of global ice-free land area contain gelisols. They are found in tundra and cold-weather environments, which has made them a hot topic of conversation as the effects of climate change are becoming more obvious. Trapped within the permafrost, contained within gelisols are large amounts of preserved carbon. Over thousands of years, during the last ice age, carbon was deposited in permafrost as ice sheets advanced and retreated. Bedrock was ground into fine silts and dust via glacial movement. This glacial flour was blown across the world and deposited, covering everything in sight, including plants and animals. Quick burial in cold environments doesn’t allow for decomposition of organic material. So as a result, modern day gelisols are a giant carbon reservoir. As climate change continues, the environments containing gelisols are more at risk of melting. Melting gelisols means that the organic material within them are now subject to rapid degradation. The decomposition of organic matter releases carbon in various forms, the most dangerous being methane. Methane is a very powerful greenhouse gas that acts to trap light in heat within our atmosphere. Hopefully you can see the problem: increasing climate change has the potential to thaw gelisols, releasing large reservoirs of methane into the atmosphere, effectively increasing the rate of climate change exponentially. Quite literally adding fuel to the fire.

new year new start

The start of the New Year is a good time to start new in the gardening year too. There is always something new to plant or try, or a method of gardening to embrace. The down-time of winter offers the opportunity to seek out something new.

Start a new plant. Visit the warmth of indoor greenhouses to lift our moods and possibly find a new houseplant. Succulents are readily available and easy to grow if you have a sunny window. Use a well-draining potting mix formulated especially for cactus and succulents to get them off with a good beginning. Water only when the top inch or so of soil is dry.

container-gardening_14_520914843

Another popular houseplant with many different varieties and forms is Peperomia. They come with solid green or variegated leaves, some with white and others with reddish hues. Textures of the leaves vary by species with some smooth and others crinkled.  All plants in the Pipericeae family are non-toxic making them safe for homes with pets and small children. Known for its low-maintenance requirements, they will happily grow in bright, non-direct light and moist but well-drained potting medium. They have a slower rate of growth, keeping them in bounds of the container for a long time before the need to repot in a larger size container.

Start a garden journal. By tracking the bloom times and placement of perennials and trees, you might see a new combination to try. Having the plant’s location marked on paper helps one to find it in the garden in late fall or early spring, when it is the ideal time to move. Monitor and record the sunlight amounts throughout the year to see how shade increases over time as neighboring trees grow taller. A sunny yard can change to part or full shade over a decade or two. Vegetable garden journals and keep track of that exceptional tomato grown last year, or maybe the one that didn’t produce as advertised. This information will help plan the next vegetable garden with better or continued success.

garden journal

Start a new class to add you knowledge base of horticulture. UConn Master Gardeners offer advanced, topic specific classes around the state. These Garden Master classes are offered to the general public at a slightly higher price than UConn certified master gardeners, and well worth it. Topics range from woody plant identification to botanical drawing. Visit the garden master catalog to view classes.

mgs

The Connecticut Department of Energy and Environmental Protection offer a wide range of outdoor classes and activities. Safety in outdoor sports is heavily reinforced if you interest is in boating, fishing, trapping or hunting. Their goal is education for you to keep yourself safe while starting a new outside activity. Classes on the environment and educational hikes are offered around the state at seven different educational facilities. 

trailhike

Start a new book. New publications in the non-fiction realm of plants include three winners from the America Horticultural Society. One is about bees and native plants needed to feed them, another on the subject of a cut flower farm, and the third is about trees of North America. There is many other great garden and plant books to start you own self-guided learning on subjects of interest to you. I was gifted the two below written by Carol J. Michel which look entertaining and educational.

books

Start anew by joining a group of like-minded plant people. Garden clubs offer talks and friendship with other members, and some have civic minded projects involving gardening, usually by town. The CT Horticultural Society offers monthly lectures to state wide members and others, for a fee, and occasional hands on workshops. They list their scheduled speakers on their website. Other groups are focused on one subject, such as the CT Valley Mycological Society where you can learn all about mushrooms and fungi. There is also the Hardy Plant Society, and the CT Rose Society. If your tastes are more specific, check out the Iris Society or the CT Dahlia Society.

“Better to see something once than hear about it a thousand times”

  • Asian proverb

There are so many places of interest in our small state of Connecticut that we should never lack for something new to do, or even to  do  again, if one really enjoyed it the first time. Here are some of the excursions that I have really enjoyed- and some of them have the added attraction of being free-of-charge, once you get there.

The West Cornwall Covered bridge is a wooden covered truss bridge built over the Housatonic River in Cornwall, Connecticut. You can drive over the bridge or walk over and take in scenic views upstream and downstream. On the eastern side there is a paved walking trail that follows the river for several hundred yards up the river on the eastern bank. This bridge is found at the junction of routes 7 and 4.

Kent Falls State Park, located on Route 7 in Kent, features a series of waterfalls that that cascade down 250 feet through the woods. The Falls Brook from the town of Warren is the stream that feeds this series of water falls, and it enters the Housatonic River a quarter mile away after completing its journey down. A hiking trail a quarter mile long is alongside the falls and, although it is steep, it is not a hard walk. There are scenic vantage points and steps built in places along the way.

Also along route 7 in Kent is Bull’s Bridge, a covered bridge that opened in 1842 and which spans a gorge along the Housatonic River.  There is a hydroelectric dam outlet just upstream from the bridge that the water passes through with enormous power. There is a small trail along the river’s edge where the noise and power of the raging water can be viewed safely.

The Thimble Islands are a group of small islands in Long Island Sound in the harbor of Stony Creek in Branford.  These islands are made up of pink granite bedrock, and they are actually the tops of hills that existed prior to the last ice age, rather than deposits of rubble that make up most islands that resulted from retreating glaciers. They are thus very stable islands and many are privately owned, and may have one to several summer homes on them.  There are tour boats that will take you on a 45 minute trip around the islands for under $20.00.

Another good trip for people who don’t mind a boat ride and a little maritime history is the Light House Cruise out of New London. Taking approximately 2 hours, this trip is rich with history and scenic views along the Thames River and into Long Island Sound. Some of the lighthouses featured are the New London Harbor lighthouse, on the west entrance to New London Harbor, the Latimer reef lighthouse on Fisher’s Island Sound, and the Race Rock lighthouse, which is part of the National Historic Lighthouse Preservation Act.

In Collinsville, there is an old factory, the Collins Company, which was a world-renowned manufacturer of cutting tools, like axes, machetes, picks and knives. Sited on the Farmington River, this picturesque factory opened in 1826. There is a trail for walking and biking along the Farmington River not too far from this old factory that can be accessed in various places on route 4.

Downtown Hartford has many points of interest including Bushnell Park, conceived by the Reverend Horace Bushnell and designed by Hartford native Frederick Law Olmsted. There are many beautiful specimen trees including the state champion turkey oak, and a double-trunked gingko. While at the park, you may want to ride the famous carousel, which is one of only three left in existence that feature the horses carved by Russian immigrants Stein and Goldstein. Downtown Hartford is within walking distance of the park and has many buildings of interest, including the blue windowed 18-story,skyscraper  at the northeast corner of Pearl and Trumbull streets.

Another good day trip is a visit to Harkness Park in Waterford. Featuring flower gardens, panoramic views of Long Island Sound, and the Roman Renaissance Classical Revival mansion of the Harkness family, this place has something for everyone. There are four 111 year old full thread leaf maple tress creating a stately grove near the owners’ dog cemetery, plus numerous themed gardens with statuary and other features. There is a stretch of beach where you can sit or take a walk, but no swimming is allowed, or you can fish if you like.

There are many more places of interest in Connecticut that make for interesting day trips, and since we have such a small state, several destinations that are near each other can be undertaken in a single day. Old Wethersfield and Old Main Street in South Windsor both have wonderful old colonial era buildings, for instance, and are a hop, skip and jump away from each other. Most of the places and trips mentioned above require little hiking, and have either dramatic or peaceful sights and sounds unique to their place in the outdoors- like rushing water, views of the sound, boat horns and perhaps the fragrance of flowers.

In my blog of October 11, 2018, I shared images and some information on various flora that are found on Bermuda and promised to talk about some of the species that have become invasive. You may wonder why invasive species on Bermuda might be relevant to us in Connecticut. Islands as small as Bermuda or as large as Australia may have species that are unique to their location and that have fewer defenses against introduced plants, animals, fungi, or microorganisms. These places are great concentrated studies in the effects of introduced species.

We have seen many invasive species become hot topics as they moved from other parts of North America or even other places on the planet into non-native locations in the Northeast. The Connecticut Invasive Plant Working Group lists over 80 plants that are currently problems, some of which moved into our region in just the course of a decade. Transported wood that is infested with the Emerald ash borer or the Asian longhorned beetle has enabled these insects to move easily from state to state.

The isolated volcanic islands of Bermuda were not subject to invasive species for most of its history. There were only 165 species of vascular plants, 5 species of bats, a species of skink and another of turtle on the islands when Bermuda was discovered. Over the next several hundred years thousands of plant and animal species were brought by ships to the islands, sometimes intentionally but more often not. Some came as stowaways as seeds in hay or soils, on ocean currents, as insects in food stores, or in the bilge water of the ships themselves.

Bermuda cedar (Juniperus bermudiana), Bermuda maidenhead fern (Adiantum bellum)

Until Bermuda was visited by the first Europeans in 1505 there had been no human-related importing of flora or fauna to the archipelago so it is a great microcosm of the effects of species introduction. When settlers come to a new place the first thing that they attempt is to make it ‘home-like’. The introduction of rabbits to Australia in 1788 by British penal colonies. Within ten years they numbered in the millions and ate enough vegetation to cause widespread erosion issues.

One of the first species introduced to Bermuda were the pigs that were released on Bermuda in the late 16th century. By the time a European settlement was established in the early 17th century the pigs had become abundant and feral. You may wonder why pigs were released in the first place. It was because the islands were used a place to replenish food and water, kind of a 17th century truck stop by ships. The pigs did untold damage to seabird and turtle breeding colonies.

Cockroaches, Periplaneta americana, came to Bermuda as egg cases in the bilges of a ship in 1621. Wireweed, Sida carpinifolia, was already a rampant invasive in 1669 when then-governor John Heydon was calling for tenants to pull it up by hand.

Many of the introduced species were brought in to control other species. The Jamaican anole, Anolis grahami, arrived in 1905 to control the Mediterranean fruit fly, Ceratitis capitata, and has since become naturalized. A beneficial introduction came in the form of honey bees, Apis mellifera. A beekeeping record dated May 25, 1617 stated that “The bees that you sent doe prosper very well.”. The Bermuda palmetto (Sabal bermudana), a native plant, is one of the main nectar sources for these bees. The giant Cane toad, Bufo marinus, an introduced species, was brought in to control garden pests but unfortunately consumes a lot of bees.

The Indian laurel, Ficus microcarpus, an ornamental garden tree was not considered an invasive species until the 1980s when a pollinating wasp was introduced to the island. Known as a strangler fig like its cousin the banyan, Ficus benghalensis, the Indian laurel can crack through walls and water tanks. It is a primary food source for the starling, an introduced species that does a lot of damage as they spread invasive seeds from the Brazilian pepper, Schinus terebinthifolia, the asparagus fern, Asparagus densiflorus, and the Indian laurel.

Indian laurel &  banyan trees

Casuarina, Casaurina equisetifolia, over-shades native plant species and causes soil erosion. It was introduced from Australia in the 1940s as a windbreak but no plants grow beneath it. Kudzu, Pueraria montana, is familiar to Connecticut gardeners as it is also on the Connecticut Invasive Plant Working Group list.

Casaurina & kudzu

With 23 of the top 100 invasive species in the world, Bermuda is still at risk of additional invasive species as most of their food and consumer goods are brought in by ship. Visitors or traveling Bermudians also bring plants, fruits, and seeds on to the islands. When you travel anywhere in the world and see warnings about bringing back fruits and plants or prohibitions against moving wood, visiting farms, or petting livestock it is for the good of all to heed that advice.

Nitrogen is an essential nutrient required for the production and growth of all plants, vegetation, and living organisms. It makes up 78% of our atmosphere; however, that only accounts for 2% of the Nitrogen on our planet. The remaining 98% can be found within the Earth’s lithosphere; the crust and outer mantel. The Nitrogen found within the nonliving and living fractions of soil represents an unimaginably low fraction of a percentage of all the Nitrogen on our planet. That tiny percent of all total Nitrogen found in our soils is what we can interact with to help or hinder plant production.

To be considered an essential nutrient, an element must satisfy certain criteria:

  1. Plants cannot complete their life cycles without it.
  2. Its role must be specific and defined, with no other element being able to completely substitute for it.
  3. It must be directly involved in the nutrition of the plant, meaning that it is a constituent of a metabolic pathway of an essential enzyme.

In plants, Nitrogen is necessary in the formation of amino acids, nucleic acids (DNA and RNA), proteins, chlorophyll, and coenzymes. Nitrogen gives plants their lush, green color while promoting succulent growth and hastens maturity. When plants do not receive adequate Nitrogen, the leaves and tissues develop chlorosis. However, over-application of Nitrogen can cause even more problems, including delayed maturity, higher disease indigence, lower tolerance to environmental stresses, reduced carbohydrate reserves, and poor root development.

The Nitrogen Cycle describes the movement of Nitrogen through a landscape. Nitrogen undergoes numerous changes that affect its availability to certain plants and organisms.

N2

The Nitrogen Cycle. Image provided by T. Morris, 2018

Nitrogen undergoes numerous transformations within a landscape; each transformation represents a distinct chemical reaction or process that acts to further Nitrogen within the cycle. The different transformations are shown in the image provided, but some important ones to keep in mind are Mineralization (organic N -> NH4+), Immobilization (microbial), Denitrification (NO3 to a gaseous form), and Leaching (the loss of dissolved Nitrate into groundwater). There are factors that determine the rates and occurrences of all Nitrogen transformations including pH, temperature, saturation, etc… All of these transformations determine how much Nitrogen is available in your soil for plant uptake. Leaching poses a big problem, when too much Nitrogen is applied via fertilizer, NO3 can be transported in the soil water. Excess leaching can lead to Eutrophication.

Most plants take in Nitrogen as Nitrate, NO3, and Ammonium, NH4+. Generally, Nitrate is absorbed much more than Ammonium, but it is all plant-specific. The combination of both of these forms of Nitrogen can help to improve over-all plant growth when compared to intake of just one. Some plants use symbiotic N2 fixation, where they supply C for fixed Nitrogen from bacteria, actinomycetes, and cyano-bacteria (blue-green algae). This process involves the transformation of N2 to NH3. For instance, Legumes use Rhizobia inside their root nodules to convert N2 to NH4.

N3

Nitrogen Fixing Nodules. Image from NC State University

Applying the correct amount of Nitrogen is key in reducing leaching, and ensuring your plants are getting the perfect amount for maximum yields. Nitrogen testing proves to be difficult because of the constant transformations it undergoes. Getting your soil tested for other micro and macro nutrients can help provide information on overall soil health, and from there, proper Nitrogen fertilizer recommendations can be made. Talk to anyone from the UConn Soil Nutrient Lab or Home & Garden Education Center for more information on Nitrogen fertilizers and soil testing.

An alarming piece of new research shows decreasing Nitrogen availability with continued global warming. As CO2 levels increase in the atmosphere, essential nutrients are becoming less available to plants. As essential nutrients become less available, forests and ecosystems that usually absorb CO2 would be unable to do so, further increasing the CO2 in the atmosphere. Oligotrophication is the term coined to describe the decreasing productivity of a forest due to the unavailability of Nitrogen. You can read more about this process in the paper “Isotopic evidence for oligotrophication of terrestrial ecosystems” in Nature Ecology & Evolution by Andrew Elmore and David Nelson from the University of Maryland Center for Environmental Science and Joseph Crain of Jonah Ventures.

goldenrod

One of many goldenrod species

Goldenrods, Solidago ssp., form one of the most interesting interrelationships between flora and fauna of the late-season flowering plants in New England. The name solidago is from two Latin words meaning ‘to make’ and ‘whole’, referring to its use as herbal remedies in the form of teas or compresses, among other uses. Goldenrods are perennial herbs that are members of the Asteraceae, or aster, family. Flowering from August through September, they are often found blooming together with Joe-Pye weeds and asters. The time of year that they bloom has made them a scapegoat for many allergy sufferers who believe they are to blame them for symptoms that are actually due to ragweed that flower at the same time.

Goldenrods naturally produce rubber, and Thomas Edison actually experimented with the cultivation process to increase the rubber content in the plants. George Washington Carver and Henry Ford devised a process to make a much needed rubber substitute from goldenrod during World War II. It was rather tacky and not as elastic as true rubber, but goldenrods and other native plants such as Asclepias and Chrysothamnus have rubber in sufficient quantity that may one day prove worthwhile. Tall goldenrod (Solidago altissima) had the most rubber content at 6.34 %.

Goldenrods have a unique type of inflorescence that consists of many tiny flowers that aggregate together in a flower head and form a ‘false flower’. The individual flowers are most commonly in the form of ray flowers or disk flowers. Identification of species is often done by observing the hairs on the seeds, which may be visible when the plant is still in flower. Goldenrods vary in height, with the tallest (Solidago altissima) at six feet. Some, such as sweet goldenrod (Solidago odora) have pleasant odors.

One of the most common goldenrods in New England is the Canada goldenrod (Solidago canadensis). It is considered alleopathic to sugar maple seedlings, producing chemicals that inhibit their growth. Habitat is disturbed areas like meadows, fields or roadsides. This is a tall plant with hairy stems and a plume flower arrangement.

It is associated with the goldenrod gall fly (Eurosta solidaginis) whose larva feed inside a round gall on the stem which is formed by the reaction of the plant to the larva’s saliva. You can easily find these galls when green or later in the season when stalks turn brown. The larva chew an exit hole before the plant tissue hardens up for the winter. In the spring, the adult fly will exit through this hole. Downy woodpeckers and chickadees will peck at these galls to access the larva, especially in harsh winters. Studies have shown the larger the larva inside the gall, the less likely it is to be parasitized by other insects or eaten by birds like downy woodpeckers in the winter. The goldenrod gall moth also causes a stem gall, but this is a spindle- shape rather than a ball. The caterpillar hatches from an egg laid the previous autumn and feeds its way into a stem.

Licorice goldenrod (Solidago odora) has a licorice or anise scent and the leaves were used in a tea by the Cherokee for colds, coughs, and fevers. This plant is found in the southernmost parts of the New England states, but is absent in Maine. Found in woodlands, along roadsides, disturbed sites and old fields, the flowers have been used to make deep yellow dyes and attract beneficial insects such as lady beetles and lacewings.

White goldenrod (Solidago bicolor) is found at the edges of woodlands. It is also sometimes called ‘silverrod’ in reference to its white flowers. It is the only goldenrod with white flowers in the eastern part of the country. The stamens and pollen will give it a slightly yellow look. Sometimes the spectacular brown hooded owlet caterpillar can be found on this plant where it primarily eats the flower buds and flowers. Found more often on any goldenrods with longer flower spikes, this caterpillar is a favorite of many lepidopterists.

Early goldenrod (Solidago juncea) gets its common name from its bloom time, which can be as much as a month prior to many other goldenrod species. This attractive, slender plant has a very delicate appearance and can be distinguished from other goldenrods by the lack of, or near lack of hairs on the stems and leaves. White-tailed deer, woodchucks, cottontail rabbits and livestock may feed on the plant if less desirable food is available.

Goldenrods provide a source of seeds for eastern goldfinch, tree, swamp and song sparrows as well as some migrating warblers such as the yellow- rumped warblers. Mice and other rodents eat the seeds throughout the winter and have a better time of it when seed heads are pressed down against the ground by heavy snows.

Any insects still around in late summer that have an interest in flowers may be found on goldenrods, especially pollen and nectar seekers and their predators. Some of the many insects and other arthropods that rely on goldenrods for survival are bees, wasps, butterflies, moths, flies, beetles, grasshoppers and spiders. Many of these visit for the pollen and nectar often in shorter supply as the season winds down. Migratory butterflies, especially along their shoreline routes, depend upon goldenrods for food sources as they travel south for the winter. Bloom periods are extended for at least two months as different species of goldenrods bloom in succession or coincide with each other.

gray hairstreak on goldenrod

Black and margined blister beetles are often found on these plants in the late summer and early fall. Many beneficial insects, such as soldier beetles and assassin bugs use the flowers as either food sources or hideouts where they wait to ambush other insects. If you see a butterfly hanging upside down without moving, check and see if an ambush bug or crab spider is feeding on it. Caterpillars such as the asteroid and flower moth caterpillars, aphids, tarnished plant bugs, and many other insects feed on flowers, stems and leaves. Wasps, goldenrod and crab spiders, praying mantids, lacewings, ambush bugs, assassin bugs, spined soldier bugs and birds prey on insects that visit or live on the plants. Cucumber beetles also feed on goldenrod pollen. Some flies cause galls on stems and upper foliage as their larvae feed.

Chinese mantids also hang out around goldenrods, and often lay their egg masses on its stems. Look for these in the winter if heavy snows have not mashed the plants into the ground. I sometimes take a stem with the mantid egg case and stick it in my garden. The mantids usually emerge by mid- May, and they disperse quickly

Mantid egg cases are often found on goldenrods where the adult females were hunting the year before. These are mantids just hatching

.

There is a great interconnection between goldenrods and vertebrates and invertebrates, and nature reveals such things to the careful observer. If you happen upon some goldenrod, or seek it out on purpose, just a few moments of careful observation will be rewarded with a peek into the drama that is on display in a simple stand of yellow flowers.

Not so wild Irish rose.

Vacations are for traveling and relaxing, seeing new lands and experiencing cultures other than our own. I did just that this summer on a trip to Ireland visiting the entire coastal perimeter of the country. I am a plant person at heart, so of course I was enamored with the plant life I saw, touched, and even ate and drank. The golden barley in the fields was to become an important ingredient in the Irish Guinness beer brewed in Dublin. We took a tour of the brewery to learn how the fruit of the hops plant and the grain of the barley are turned into the well-loved stout beer.

Along the coastal route we traveled, we did not see many vegetable farms as they were located more inland where there were better growing conditions and soil. We did see many fields with sheep and cows. Beef and dairy cows were often feeding in fields not used for hay.

Often large fields would have a lone, ancient tree standing within its boundaries, and could be any species that happened to take root on the spot. Our tour guide told us those trees are known as fairy trees which house the fairies of Ireland. Fairies in Ireland are not nice and cutesy like we Americans think of them. In Ireland fairies are tricky beings, and can bring havoc and bad will to those who disturb them. For this reason, farmers will leave a large tree in the middle of his field, even driving around it when seeding and growing crops, avoiding tilling up the area so as not to disturb or offend the fairies residing under it. The superstitions are handed down with the generations, and many stories of them may be found in bookstores on the local legends.

Fairy Tree

Magical Fairy Tree. Can you see the fairies?

We passed peat bogs which are wetlands covered in accumulated dead plant material and mosses. Peat takes centuries to form under the acidic and anaerobic conditions. Layers of peat were traditionally cut out of the bog, left to dry and then used a fuel source to burn inside fireplaces to heat homes. Now a day, modern heating is used in Ireland, and bog management laws limits on the amount of peat harvested. Peat moss used in gardens is also harvested from bogs. Since it takes centuries to form, it is not really a very good renewable resource.

 

In windswept, boggy meadows along the seaside were plants that looked like cotton blowing in the wind. It is called bog cotton, Eriophorum angustifolium, a grass-like sedge plant with fluffy seed heads. Each seed is attached to a fluff of hairs/bristles that can catch the wind to be carried far away. Great method of seed dispersal created over eons to ensure the survival of the species.

Foxglove is a native weed just about everywhere in Ireland. Its purple nodding bells arising from waste areas and rock walls. Called Fairy Thimbles in folklore, they are deemed unlucky if you bring them into the house in case you let a naughty fairy into the home. Foxgloves are biennial, with second year plants blooming from June through August.

While in Northern Ireland at Malin Head, I came across the most unusual hedge plant planted in multiple yards and outside several establishments. After asking a local or two, its identity was revealed as Hebe, a broad leaved evergreen plant with showy purple flowers in July and August. It is native to New Zealand and the folks I spoke with weren’t sure how it originally came to their town, but they share it readily with neighbors. Hebe is hardy there, but will not take temperatures below freezing. Even one exposure to a freeze and its top growth will die back. The stands of I saw were happily six feet tall and tolerating even this northern most town on the coast.

What would a visit to Ireland be without the mention of potatoes? Several museums and tour guides told the history of the Irish potato famine caused by the fungal disease of late blight, Phytophthora infestans, the same disease that infects tomatoes and can wipe out a crop. The English withheld all other food sources from the Catholic following Irish people unless they denounced their religion. Once the potato blight hit for several years, there was no food left resulting in mass deaths and migrations to other countries. Still today, the entire population of Ireland has not reached the numbers it had before the blight hit.

At the end of our trip, we packed up our mementos of Irish lace and tweed caps along with the rich stories of Ireland. My memory cards are full, both the physical one in my camera, and the one in my head.
