Horseweed
Erigeron canadensis
Horseweed is an extremely hardy annual that thrives in disturbed soils and requires virtually no care. It self-seeds prolifically and can become weedy, so deadheading before seed set is recommended. This tough plant provides late-season nectar for pollinators when few other flowers are available.
