Invasive plants are a challenge for any gardener. With so many different species, and more appearing all the time, how do you know which plants are invasive? Longwood Gardens Senior Ecology Technician Joe Thomas will help take the mystery out of identifying invasives in this two-part class. First, join Joe for an online orientation where he will explain key features used to differentiate between many common invasives, including Oriental bittersweet, Autumn olive, and Small carpet grass. Then, join Joe at Longwood in our Meadow Garden to get hands-on experience identifying these species in the landscape.

Dress appropriately for the weather, and wear comfortable walking shoes, as you may be walking on uneven paths and wet areas.

Inclement weather date Sunday, September 16.
