Monarda didyma July 8 2011I know my woodland garden is entering a new phase when the beebalm starts blooming. Summer and humid days are here, the canopy above is much more stingy with letting light through (even the caterpillar damaged twigs are sprouting new leaves), and lush growth is all around. At the same time days are getting noticably shorter already and I can’t help but think that fall is right around the corner.

Beebalm announces my red period, if my garden were art. I have lots and lots of beebalm, mostly the scarlet native variety, but a few cultivars also, with deeper shades of red and even purple. Cardinal flower will soon join the fray. After this comes a prolonged yellow/blue period, up to frost…

Monarda didyma is native to eastern North America and produces beautiful red flower tufts on long stems with dark leaves. It produces a minty aroma, which was recognized by native Americans and early settlers who made tea from the leaves when no proper tea was available. There are other kitchen uses as well: The flowers can be added to salads as a garnish, and the dried leaves can replace oregano in cooking. Its crushed leaves, which have a peppery flavor, can be applied to bean dishes, pasta, pizza and stews as seasoning. However, the main reason I have the plant in my yard is because it is a major hummingbird nectar source.

Linnaeus named the genus Monarda in honor of a 16th century Spanish physician and botanist, Nicolas Bautista Monardes (1493-1588). Monardes never got to see the plant in its environment but was able to study medicinal plants in his homeland since the Spanish controlled much of the new world.

Bee Balm is a heavy feeder and a good organic mulch will help keep it going. Also, the plant has somewhat of a habit of dying off in the original spot planted. You should disturb the soil and let it grow back in from rhizomes from outside that location.

Later in the summer, you may need to stake it as it becomes susceptible to being blown over by high winds, especially when in bloom with the heavy flowerheads. You also need to watch out for powdery mildew – this will lead to leafloss. Some cultivars are mildew resistant, or so it is claimed… You can force the plant to produce flowers throughout most of the summer. Cut off the dead flowerhead just above the leaves below it. You will get two new flowers…

moneywort July 1 2011I noticed this flowering creeping perennial at the wildflower garden at the Museum of Natural History. I thought “how lovely” because I had no clue what it was, initially. Moneywort, as this turned out to be, is native to Europe, and was introduced in North America as a horticultural plant. It first got here in 1739. It has escaped from cultivation and spread extensively. Moneywort seeds were sold in the United States as early as 1833, and it was established outside cultivation in the United States by 1900. I am not sure if its presence at the garden was intentional or not, but there it is.

As a side note, non-natives frequently come along with plants bought from nurseries. They are sometimes grown side by side and seeds or seedlings can make it into the potting soil or pots respectively. At the same time, invasives are everywhere and they are equally free to disperse their seeds into the environment.

moneywort July 1 2011

As for moneywort, it can be an agressive plant especially in wet and moist conditions. In some states it has been banned from being sold. It often wanders out of gardens into the woods, where its spread and impact is difficult to control and gauge.

Lotus corniculatus July 1 2011This yellow-flowering perennial is native to Europe, Asia and North Africa, but can now be found worldwide. The name comes from the leaves that seem to be arranged in threes, resembling a flat-footed bird’s foot. In actuality those are just the most visible leaves out of a quintet. The plant will flower until September and will then generate seeds.

The plant grows a few inches high to multiple inches, depending on the height of the surrounding plants (mostly grass) and the extent of grazing by animals. It has been grown for foraging purposes for cattle, and for the fact that it fixes nitrogen in the soil. I have found it in my woodland garden, but it barely produces one or two flowers due to the lack of sunlight. Elsewhere, with sufficient light, it grows in massive yellow patches.

The plant is poisonous to humans: It contains hydrogen cyanide, which (in small doses) can stimulate respiration and improve digestion. Some say it can be used in the cancer treatments. In large doses it will cause respiratory failure and even death.

detail of swamp milkweed July 8 2011This milkweed is a tall native plant which is usually found in swamps, near rivers, and wet meadows throughout most of the United States (It is not native to the western states). It reaches 3 to 5 feet and is now producing clusters of small, pinkish flowers. These flowers are an important food source for butterflies. The leaves are lancelike.

Asclepias prefers full or partial sun, and wet to moist conditions – it will even tolerate standing water for periods of time. On the other hand, the plants will be smaller in dry conditions, although the plant will do fine in well drained soil as long as adequate watering occurs.

This milkweed species is considered toxic and should not be eaten (as opposed to common milkweed which has culinary uses)

common milkweed July 8 2011It’s nice to see these milkweeds popping up everywhere, alongside roads and in meadows. The plants don’t require much tending – they prefer dry well-drained soils and full sun, and will do fine in poor soils as well. Common milkweed is quite drought tolerant. The plant can be grown from seed, and will readily self-seed. Additionally, common milkweed will spread by rhizomes.

This perennial, native to most of the United States except for the western states, grows 3 to 6 feet tall, and has broad, somewhat shiny, leaves. It has ball-like, slightly drooping clusters of pink and purple flowers. The stems and leaves produce a milky sap when cut or bruised – it is “milkweed” after all. In the fall, the flowers will produce seed pods that look like a pita or bread pocket. These pods will split open and release seed that is built perfectly for wind dispersal – they have silky feathery attachments.

Common milkweed feeds many butterflies, but in particular the Monarch butterfly. Its caterpillars feed on the leaves of this plant.

Asclepias syriaca is apparently quite edible. Sure, all parts of the plant have some toxins, but consuming the plant raw in small doses is fine. When dealing with larger amounts, boiling and cooking will eliminate the residual toxins. The following electronic re-publication of a 2003 Forager’s Harvest article illuminates the many uses, culinary and otherwise, of common milkweed. Well worth a read. I may stick to propagation solely for the benefit of butterflies, peronally…

Pyrola sp. July 8 2011Myco-heterotrophy, the relationship described in an earlier post about the indian pipe plant, is not so uncommon, and can be found in several different groups of plants. The monotropes, the liverwort Cryptothallus, and non-photosynthetic orchids are full-time myco-heterotrophs. Some plants are partial myco-heterotrophic, and others can switch back and forth, or are myco-heterotrophic at one particular time (Some ferns and clubmosses are myco-heterotrophic in their gametophyte stages).

The fungi that are parasitized by myco-heterotrophs are typically fungi with large energy reserves to draw on, usually mycorrhizal fungi (which get their energy from a host plant or tree).

The genus Pyrola (or wintergreen) in the Ericaceae family of plants contains species that can live both photosynthetically or not, and they have either leaved or leafless forms. The latter plants are totally dependent on the mycellum they feed on. Pyrola, or wintergreen lives in damp and dark places where there is plenty of leaflitter, and of course, fungi.

Pyrola sp. July 8 2011

I found this particular wintergreen in the darkest possible place in the Bridge Street conservation area in Barnstable. It has the thick arrangement of flowers often seen in Pyrola minor (snowline wintergreen), but Cape Cod is too far south for its range. Is this Pyrola americana (american wintergreen), or another Pyrola species? This particular plant had no basal leaves. Can anyone help me identify this species?

Rudbeckia hirta July 8 2011This plant is spectacular when it is doing well. I’ve had mixed results. None of the plants survived from last summer. True – they can be annual or biennal plants, but in some cases or situations they are perennial. I think the drought did them in last year. This year, I had some good strong plants going, until the rabbits discovered them. I believe Rudbeckia hirta is deer resistant, but the bunnies eat leaves as well as flowers – they have the annoying habit of gnawing the stems halfway so the flowers topple to the soil, making for easier consumption, no doubt… I have a few in a flowerbed closer to the house that have remained intact. Blackeyed susan is a must-have though, despite the rabbit problems and the fact that I get contact dermatitis from this plant. It attracts scores of bees and butterflies.

Rudbeckia hirta July 8 2011

Some interesting facts: Rudbeckia is named after Olaus Rudbeck the younger (1660 – 1740) who was Linneaus’ botany teacher at the Swedish university of Uppsala. Hirta means “hairy” in Latin.

Early settlers used the plant as a stimulant and a diuretic. They brewed a tea from the dried leaves to use as a stimulant for the kidneys. Native Americans also made a tea from the root to relieve colds.

Medicinal Uses: An infusion of the roots has been used in the treatment of colds, and worms in children. A warm infusion of the root has been used as a wash on sores and snake bites. The ooze from the roots has been used as drops to treat earaches.

Some folks (count me in) are sensitive to the plant and can get contact dermatitis or rashes.

Monotropa uniflora July 8 2011This is one of the more interesting plants on Cape Cod – it has no chlorophyll, and therefore no green leaves, so it cannot obtain energy from sunlight. Instead, it gets nutrients as follows:

In the leaves of a nearby tree, or photosynthesizing plant, carbon dioxide is turned into sucrose, which is transported to the roots. A fungus, feeding off the roots of the tree, takes the sucrose and transforms it into sugar alcohols, which are taken troughout  the fungal mycelium (some of these can be large – I believe the largest organism on the planet is a fungus many miles long).  Poor tree, you say.  Well, it’s not exactly like that – the fungus sometimes helps the tree with the absorption of water and essential minerals.  As for the indian pipe – it absorbs the sugars from the fungus.  Sometimes it does take three to tango!

indian pipe July 8 2011

I see Monotropa uniflora now and again in my woodland garden, but they are more prevalent in dark moist woods with lots of leaf litter.  The walking trails in the Bridge Street conservation area off Route 149 have lots of indian pipe plants.

So what are club mosses anyway? They are flowerless and seedless plants in the family Lycopodiaceae, that belong to a very ancient group of plants. they were the dominant plants during the Coal age (360-286 million years ago) and many were shrubs or large trees. We are very likely consuming these plants in the form of coal or petroleum. By 250 million years ago, most of the woody species had died out. There are currently some 400 species known worldwide. You will find club mosses anywhere from the arctic to the tropical regions. Nowadays they no longer dominate plant communities. In arctic and temperate regions, club mosses are terrestrial; whereas in the tropics, they are mostly air plants (attached to branches or tree trunks, although not parasitically) near the tops of trees and are seldom seen.

Walking the Bridge Street conservation area in Barnstable last Friday, I discovered two distinct species of this ancient family:

Lycopodium digitatum (fan clubmoss)

This clubmoss has a cedar-like appearance, low growth, evergreen leaves. Its spreading habit make it ideal for the well-drained eastern woodland landscape. Once established, it spreads quickly by stems that lie just at the surface of the soil. This particular species was particularly abundant in a clearing at higher elevation where the soil was fairly dry.

Lycopodium dendroideum (tree groundpine)

This particular clubmoss is somewhat difficult to distinguish from Lycopodium obscurum, and in the past it was even considered a local variety of the latter. To be honest, I may be wrong about what this is exactly – I am by no means a club moss expert – If I am indeed wrong I hope you will correct me. The tree groundpine is being harvested to be used in Christmas decorations. This club moss is found in the wetter and darker areas of this particular wooded area.

Beauty of the beast

The beauty of this hairy caterpillar is quite astounding. Unfortunately, in this case beauty belies the true nature of this animal. This is a gypsy moth caterpillar, and these pests have been ravaging the white oaks in my yard for many years now. Eventually they may become just too much for the trees. Huge areas of trees have already died on Nantucket and the Vineyard, and I’m pessimistic about the changes of oaks everywhere over the long run. Ironically, others critters don’t care much for beauty – this caterpillar got picked off the branch by a catbird less than 5 minutes after taking the picture. Sweet justice!
