Oriental bittersweet: Eradicate, Don’t Decorate

Oriental bittersweet: Eradicate, Don’t Decorate

Oriental bittersweet (Celastrus orbiculatus) is a climbing deciduous woody vine that thrives in disturbed habitats (e.g., roadsides, forest edges, riverbanks, etc.). This plant can grow rapidly, shading out and/or strangling native plants, including mature trees. In the fall and winter, after the leaves have fallen away from the bittersweet vines and the surrounding vegetation, the bright three-sectioned red-orange fruits and their yellow outer “husks” can draw your attention from quite a distance. As the capsules dry, they hinge open, revealing…

Intertidal Invasion

Intertidal Invasion

These days, with globalization driving long-distance dispersal of species ranging from fungi to insects to plants, the term “invasive species” gets used a lot. To me, there is a difference between “non-native” and “invasive”. Although both terms refer to an organism that was not found here prior to colonialism, the term “invasive” is typically reserved for organisms that have not only established outside their native range, but have thrived and spread to the point of being a nuisance and can…

Glossy Buckthorn (Frangula alnus)

Glossy Buckthorn (Frangula alnus)

I think my most common summer phrase is “berry season is the best season”. I’ve been thoroughly enjoying wild-picked blueberries, huckleberries, red and black raspberries, and wineberries, as well as  the blackberries that are just now starting to ripen (I picked my first ripe one this morning). Now that my eyes have a “berry” search image, there’s one shrub I’m noticing everywhere: glossy buckthorn (Frangula alnus), which grows as a deciduous shrub or a small tree up to 20 feet…

Wild Edible Recipe: Garlic Mustard Pesto

Wild Edible Recipe: Garlic Mustard Pesto

This past weekend my boyfriend and I went for a walk to gather stinging nettle for dinner, and came across a large patch of young garlic mustard (Alliaria petiolata) as well. One of best parts about picking garlic mustard as a wild edible is that it’s also incredibly invasive, like Japanese knotweed and autumn olive. So you’re doing the ecosystem a favor when you harvest it. In fact, one of my wild edible books describes garlic mustard as “universally despised…

Scotch broom (Cytisus scoparius)

Scotch broom (Cytisus scoparius)

While birding along the Cape Cod Canal on Saturday, I noticed a fairly large clearing filled with green, densely branched low-growing shrubs. Upon closer inspection, the stems were strongly angled with alternately arranged pinkish-brown buds. Even without leaves or flowers, it did not take long to identify this shrub as Scotch broom (Cytisus scoparius). This non-native shrub flourishes in full sunlight in dry, sandy soils, making it no surprise that it was so abundant in this Cape Cod clearing. Scotch…

Winter Moth (Operophtera brumata)

Winter Moth (Operophtera brumata)

I love warm rainy nights in December. Not because I particularly like rain, but because I love how winter moths (Operophtera brumata) emerge seemingly out of nowhere, to take advantage of the warmer weather. In fact, they’re one of very few Lepidopterans in the temperate region that are active in the late fall and early winter. On nights like we had this weekend, with light rain and temperatures close to 50 degrees, they can be so numerous that they remind…

Dead Man’s Fingers (Codium fragile)

Dead Man’s Fingers (Codium fragile)

Most of what we call “seaweeds” are actually marine algae, not plants. Algae differ from marine vascular plants, such as eelgrass, in that they are more primitive and lack specialized structures such as seeds and flowers, although most do photosynthesize. Seaweeds are often categorized by color: red, brown or green. Codium fragile is a green marine algae that is easily identified by its thick dark green, rope-like, spongey branching form. These branches are soft with a velvety texture. Codium has…

Porcelain Berry (Ampelopsis glandulosa)

Porcelain Berry (Ampelopsis glandulosa)

Porcelain berry (Ampelopsis glandulosa var. brevipedunculata), also known as Amur peppervine, is easily recognized by its showy clusters of pink-purple-azure berries. These colorful fruits are the reason this perennial vine was brought to the United States in the 1870s from East Asia as an ornamental groundcover. Although originally intended for landscaped areas, its fecundity and adaptability have allowed it to spread readily into wild areas, and in many cases porcelain berry vines can completely smother the native vegetation. A vine…
