With so many different species, and more appearing all the time, how do you know which plants are invasive? Join Longwood Gardens Research Specialist Tabitha Petri as she takes the mystery out of identifying invasive plants and how to manage them in your home garden. You’ll begin in The Grove, where Petri will explain key features used to differentiate between many common invasive plants. Then, join Petri in the Gardens to get hands-on experience identifying these different species in the landscape.
