We bought some last year, desiring to replace many of our plants and flowers with natives. They bloomed beautifully then and are coming back again this year. I have such a hard time getting anything to grow, that I will give any small success a positive rating.

We planted these on the north side of the house, and it gets partial shade. They seem to do nicely in that area.

This plant is extrmely hardy. I live in Reno,Nevada,and deer are everywhere. Suprisingly, the deer did not have any interest in it. The flowers are big with a black center, and yellow petals.
