Hybrid Columbine perenial
I planted it in May and it bloomed beautifully in a part sun/shade area next to a Phlox plant. It is done blooming and parts of the plant are turning brown and pull easily from the ground. I don't know enough about them to know what is happening. I don't have a picture I can upload.
Columbine often goes dormant in the heat of summer. Bleeding heart does the same thing. You may see leaves return with cooler weather or the plant may stay dormant until next spring.
