How bleeding heart fits zone 6's season

Zone 6b's frost-free window runs about 173 days, from April 25 to October 15. Bleeding Heart takes about 1 growing season to reach full flowering, so what matters here is how many of these seasons it gets, not whether one is long enough.

Bleeding Heart is hardy in zones 3-9, so in zone 6b it stays in the ground through winter and comes back rather than being replanted. Allow about 2 ft of spread at maturity.
