Answer: Dicentra, or Bleeding Heart, is an interesting plant in that it grows quickly in the spring, flowers in early summer, and then the top of the plant dies down. The roots rest until the following spring and it's then that they produce new stems and flowers. It's best to plant Dicentra roots in fall or winter (they're sold in sawdust packed boxes, just like bare-root roses).
Hope this answers your question!
