In January, this bioswale was seeded with a native wildflower seed mix from Missouri Wildflowers Nursery. Unlike fescue, it takes some time for wildflowers to start growing. Finally in early June we saw some positive signs, the coreopsis began to bloom. Then a few weeks later, lots of natives started really growing. The bioswale has gone from sparse to filling out!

A bit of weeding was necessary to stymie the Johnson grass and ragweed from taking over. A variety of natives are emerging including Partridge Pea (Cassia Fasciculata) and Coreopsis.

Native plants require some initial maintenance, but in the long term, this swale will require mowing only once per year in the fall. This bioswale will probably be over seeded with more natives this fall to force out weeds and fescue.
