Ck, we also have something that strips the columbine of foliage. They are small caterpillars but I don't know which ones they are so I leave them. It hasn't been bad this year. So sorry for your yellow columbine. Thanks Bip. Cris, thank you. My camera's so small it fits in my pocket. I crawl about on hands and knees to photograph some of our plants so a tripod wouldn't do any good. I'm certain your iPod camera is more than adequate.
