Columbine Flower Behavior
Date: Fall 2011
My yellow columbine flowers are constantly opening and closing throughout the day AND the night. I can't find a single thing on the internet that says columbines are supposed to do this. Is something wrong with mine?
Flowers can open and close depending upon environmental conditions (light, temperature, humidity).
