There are a million different colors of Columbines.
I can exaggerate like that because, at some point, in the future of this delightful perennial, it could actually come true.
Did you know they hybridize themselves every season? Plant yellows and purples adjacent to one another and the next year you will very likely see a brand new color. Or, a variegated purple and yellow!
* Most prefer partial shade -- this happy little Canadian Columbine does best in full sun, hot, dry, conditions.
** It does not reseed as readily as the many hybridized Columbines.
