Perfect flowers

Haven't posted a columbine photo in a few days. At this point, this guy is winding down and its the yellow columbine that is putting on a show. However, only 1 out of the 6 I grew from last year have flowered (the pink and yellow one) and it turns out that I planted mixed coloured seed, so I'm waiting to find out what colour the other 5 are, assuming they flower this year.
