Evil Weeds - Jewelweed

Day 330: Native in some parts of the United States, Jewelweed (Impatiens capensis) is considered invasive in the Pacific Northwest, and rightfully so. Just in the years I've been working with the Invasive Plant Council, I have seen it take over acres of wetland within two or three years from the time of the first observation. It is often found along lakeshores and river banks, factors which contribute to the dissemination of the seed. Where it is accessible, it is easy to remove by pulling, but locations where it occurs should be monitored closely for several years in order to eliminate any latent sprouts.
