I love this plant!!! It does well no matter where I put it. It even tolerates light shade. Dead-heading regularly promotes more flowers. Roots tend to be shallow, so keep protected from strong winds. Mine is about 2' tall. The entire flower (including the center) is yellow.

I purchased a can of wildflower seeds in 2000 and this is the only survivor of the bunch. It has propagated by resowing itself every year. It has become a bright spot in my garden and does very well with very little care. I have very heavy clay soil. I put a new layer of mulch on every year and feed with Miracle-Gro.
