Japanese barberry is an invasive plant, and probably one of the most destructive invasive plants in Connecticut. It can form thick stands that exclude nearly all native plants. The seeds are spread over long distances by birds. Please don't add to the problem by planting Japanese barberry in your yard! More on this plant from Invasive Plant Atlas of New England.
