As spring arrives in Richmond, the fragrant blooms of wisteria plants can be seen climbing up fences, buildings, and trees. However, many of these wisteria plants are actually invasive species that can be harmful to the local ecosystem. This article provides tips on how to identify native versus non-native wisteria, as well as a community-driven online map to help track sightings of the invasive plants.

Why it matters

Invasive wisteria species can quickly overtake and damage native plants and trees, disrupting the local ecosystem. By educating residents on how to identify these invasive plants, the community can work together to monitor and manage the spread of wisteria in the Richmond area.

The details

The invasive wisteria species typically bloom in March or April, earlier than the native American wisteria which blooms in late spring or early summer. Invasive wisteria can grow rapidly, winding tightly around host trees and constricting them. The iNaturalist online platform allows users to submit sightings of wisteria and other plants, helping to create a community-driven census to track the spread of invasive species.

  • Invasive wisteria typically blooms in March or April in the American South.
