Thank you Vic, Tee, and Mary, I'm so pleased that you all like it!
Mary, the plant on the left with the 2 colors is a different plant, the one on the right has all yellow blooms, they grew so close together that sometimes the stalks intermingles and looks like one. If you would like to grow them just pick up a package of mixed Columbine seeds, they are easy to grow, very hardy and once established are quite drought tolerant as they send their roots really deep into the ground. They do need at least semi-shade in the afternoon.
