 Why is it a noxious weed?

Spotted jewelweed has spread rapidly since it was first documented in Washington. Plants are widespread in certain lowland areas and appear to still be increasing. Seedlings of spotted jewelweed can form dense carpets that can compete with native species and are difficult to control.
