How bleeding heart fits zone 8's season
Zone 8b's frost-free window runs about 230 days, from March 25 to November 10. 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 8b it stays in the ground through winter and comes back rather than being replanted. Allow about 2 ft of spread at maturity.
