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.

My first time with this plant.[purchased at Lowes] Get many comments from folks who pass my yard. Easy to grow and low water needs plus good looks. A+ for SoCalif.

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.
