Ratibida columnifera is known as the Mexican Hat flower. The elongated center disk gives it a resemblance to a sombrero. The colors make it perfect for fall and I find it grows well here, but tends to be short lived. On the plus side, it also tends to self-seed. There are a couple of Ratibida species that grow here as well as a few cultivars and they all tend to cross pollinate, so be prepared for some surprises if you grow more than one.
