Second Annual Poison Ivy Day
You didn’t know? Well, it’s true. April 1, 2015 is officially the Second Annual Poison Ivy Day. You missed the first Annual PI Day? For goodness sake, you need to pay closer attention! Virginia is the pioneer state on this one, but we are pretty sure others will be following our lead by next year. California…
Manage White-Tailed Deer to Protect Our Natural Heritage
Most residents of Virginia understand the need to change human land use practices to stop or minimize habitat destruction and preserve our native plant communities. An increasing number of people also support combating the spread of non-native invasive species to include problem plant species and insects such as the emerald ash borer beetle which girdles…
The Living Landscape: Summary of Rick Darke’s Talk
Rick Darke recently gave a talk on his new book, co-authored with Doug Tallamy, The Living Landscape;  sponsored by our Prince William Wildflower Society Chapter and delivered to a full house of over 180 attendees. This new book is much more than a traditional “how-to” design manual. It is a thoughtful analysis of the natural harmony of relationships…
Hope and Reality for Urban Ecosystems
Years ago, I served on Maryland’s Plant Reintroduction Task Force, which was largely convened to address the merits, legal ramifications, and biological soundness of reintroducing rare taxa “recently lost from its historic range” or to enhance dwindling populations that remained in their historic natural settings (PRTF 1999). Specifically at the time, this involved a proposal…
Meet The Witch Grasses!
​Grasses are often overlooked and dismissed as difficult to identify – too technical and cryptic. No wonder, then, that the enigmatic witch grasses (genus Dichanthelium) have really gotten the short end of the stick. It is at least worth your while to know that these little grasses are quite successful and diverse. Most habitats in…
Adventures In Plant ID
Every chair was taken and extras had to be brought in for the first of the Piedmont Chapter’s Winter Speakers Series this afternoon in Marshall, VA. An appreciative audience paid close attention as the speaker, Richard Stromberg, revealed some of the tricks of his trade during his talk: ‘Adventures in Plant Identification: Tools, Tips, and…
The Habitat Game
Games are a great way to get people to learn, and the Piedmont Chapter has invented a cool (tested!) activity to teach the concept that our choices in landscaping make a difference, and why. This article first appeared in the Chapter’s Winter newsletter, The Leaflet. We’re happy to have the opportunity to spread the idea…
Winter Solstice Field Trip and Hooley, 2014
Many thanks to all the participants, over 60 in all, who made the December 21, 2014 Winter Solstice Field Trip and Hooley at Ferry Hill, Washington County, Maryland such an enjoyable and memorable outing! This event, traditionally held at one of the region’s old-age forest communities, is always a great way to welcome the winter…
Landscapes of Memory
Venus Flytraps near my Grandparent’s home in coastal North Carolina were the first plants that caught my interest. Like many kids, I was fascinated by the idea of carnivorous plants, but until reading an article in National Geographic, I had no idea that they lived so close to a place I visited frequently. I begged my parents…
Gifts for Gardeners and Native Plant Lovers
Just in time! Ideas for the most desperate among us, the ones who haven’t yet crossed even the first gift off our list. You know who you are. On Black Friday you were either out transplanting just one more shrub, or you were off wandering on some leafy trail noticing which trees had already…
Non-Native Milkweed: Helpful or Harmful?
The most recent article about the monarch butterfly in the New York Times has once again raised the question of whether we should be planting non-native milkweed. The milkweed being discussed was the tropical variety most widely available in the usual stores, Asclepias curassavica, known commonly as Scarlet or Tropical milkweed. Ongoing research points…
One Chapter’s Call to Action
As far back as last summer, the Potowmack chapter had decided to do something different at its Annual Meeting. Board members would still have to be elected, of course, and a budget passed. After that part of the meeting, the chapter had always in the past offered a field trip or walk, but this year,…
