I have two columbine patches in a light woods. One red and the other blue. This year most plants didn't appear at all until August. I'd assumed they'd died, but now there are little 2 to 4 inch plants. But these plants range in age from 2 to 7 years. They are all marked. Needless to say I had almost no blooms. The weather hasn't been striking... slow spring, very dry August. Any ideas about what might have caused this?
