Yellow flowers on a green landscape.

Prairie Home


This drought-tolerant member of the Aster family grows to a height of one to three feet. It can grow in all sorts of environments and soil types, and is either a perennial or a biennial, depending on the location. The stem and leaves are bristly, and the flower is a dark yellow with a dark brown or black center disk.

It is visited by many pollinators including bees and butterflies. The flowers often host ambush predators, such as jagged ambush bugs, assassin bugs, and crab spiders, that lie patiently in wait for pollinators to arrive.
