Flickweed (Cardamine hirsuta) is a fast-growing annual weed that commonly invades lawns, gardens, and disturbed areas. It features small, pinnate leaves and produces tiny white flowers. Flickweed is known for its explosive seed dispersal, which can quickly spread the weed over a large area. Effective control involves maintaining a healthy lawn, regular mowing, and using selective herbicides specifically designed to target Flickweed.
