Dicentra spectabilis usually goes dormant in summer. Dicentra Exima will keep it's foliage and bloom through summer. Either can be cut back if the foliage has become unsightly.

I find that my dicentra exima (the "common" or "wild" bleeding heart) stops blooming during the hottest summer months, and the foliage thins out considerably. As soon as summer's worst heat passes, it puts out lush new foliage and a second flush of bloom. I'm seeing that process beginning now, with a few just beginning to re-bloom. All are growing in high, dappled shade, some with early morning sun.
