Eup! There It Is: An Introduction to Thoroughworts

Imagine you’re exploring a Piedmont grassland remnant in early August. In the summer heat, the grassland comes alive with the fresh green growth of little bluestem (Schizachyrium scoparium), yellow prairie grass (Sorghastrum nutans), and other warm-season grasses. You spot the bare seed heads of Small’s ragwort (Packera anonyma) whose flowers lit up the grassland in rich yellow during the early summer. Ah, the starry rosinweed is in full bloom, its cheery butter-yellow flowers buzzing with the activity of native bees that dash here and there. And as you look out across the remnant, you see so many white puffs spanning the grassland you wonder if you’ve discovered patches of clouds given vegetable form. These, too, are buzzing with insect visitors—sweat bees, bumble bees, wasps, flower flies, beetles, and more—such an abundance of pollinators that trying to track them all is dizzying. What you’re seeing, my friend, is the fascinating genus of thoroughworts (Eupatorium spp.).

What Native Plants Should I Put in My Yard?

Every day, I see people asking in person and online, “What natives should I plant in my yard?”

Oftentimes, the answers given are very generic and do not serve biodiversity. We have lived our entire lives under the paradigm of Euro-colonial horticulture, where the value of a plant in the landscape is dependent upon its “performance”, by which we mean how well an individual species can grow under certain conditions in the domestic landscape, and how closely it adheres to the aesthetics of the formal style of American landscaping popularized as a way of imitating the British aristocrats of yesteryear (who collected plants from around the British empire and were able to maintain unnaturally perfect lawns and gardens through armies of servants). This individualistic method, focusing on selecting an assortment of individual species based solely on novelty and/or appearance, results in what are known as novel ecosystems, which contain mixtures of species from around the world with little or no shared evolutionary history, and which would not exist without modern human behavior.

Tropical Plants in Your Backyard

As I sit by my computer, I glance out the window at the cold landscape outside. Trees bare of leaves stand like solemn sentinels against an overcast sky that looks down on a drab world of grays and browns. You can almost feel the chill just by looking out the window, and I dream of a winter getaway in some tropical land filled with all manner of strange and wonderful plants that would never survive winter in temperate North America. 

Asclepias, A Genus of Wonder

Hello! I’m David, the newest member of the PDC team and I’m here to tell you about one of my favorite groups of native plants, the milkweeds (Asclepias spp.). I have always been fascinated with their complex pollination system unique to the genus, their ecological importance, and their pleasing flower displays. My interest only grew when, in 2018, when I had the opportunity to go to the Missouri Botanical Garden in St. Louis MO to assist with a project to help conserve Mead’s Milkweed (Asclepias meadii), a federally threatened milkweed from the tallgrass prairies of the Midwest. I’ll give a brief overview of the genus, its importance and highlight species found in the Piedmont region of Virginia. By the end of this article, I hope you’ll become a milkweed fanatic too!
