Garlic mustardDo natives and invasives coevolve?
Well, yes, according to researchers at the University of Georgia. A new study reveals that some native clearweed plants (Pilea pumila) have developed a kind of resistance to the aggressive garlic mustard—and here’s what’s creepy—the invasives appear to be waging a counterattack. Garlic mustard is successful because it produces a compound (sinigrin) that kills fungi essential to native plants’ survival. In lab tests, however, researchers showed that native clearweed—which tends to occupy the same habitats as garlic mustard—shows higher levels of resistance to sinigrin where the two plants have coexisted over time.

University of GeorgiaAssessing risk of plant imports
Busy times at UGA: A new model developed by researchers at the University of Georgia and the University of California-Davis provides a “cost-sensitive” way to help determine the risks of importing plants. In short, the first step is to assess how likely a plant is to become invasive, using four simple criteria. If the plant leans toward potential weediness, an economic rule is applied, weighing the value of the ornamental plant in trade vs. the costs associated with eradicating weeds. If costs outweigh value, it’s a no-go. That’s an oversimplified summary, so click on the link here to learn more. It’s interesting stuff. Read more>

Integrated Landscaping: Following Nature’s LeadBuy this book!
Integrated Landscaping: Following Nature’s Lead is a valuable resource for anyone concerned with helping to shape the landscape. When we see ourselves as part of the whole, we can see that what we do in places where we live, work, and play has a ripple effect far beyond the space each of us calls “home.” Most landscape manuals describe a linear sequence of processes: design, plant selection, installation and ongoing maintenance. Integrated Landscaping is different. It uses natural ecosystems as models, taking a nonlinear, holistic approach that addresses these processes simultaneously. The authors treat each site as a system of plant and animal communities, considering their interrelationships with each other and their environment. Read more>
