Hi, When will a bleeding heart usually start to bloom given healthy conditions in Toronto? When should a new bleeding heart plant be planted. I’m thinking around May 1. Is that right?
Thank you for your question. Yes, a bleeding heart will bloom in Toronto (Zone 6).
Bleeding Hearts can be planted in fall or spring.
Bleeding hearts (Dicentra spectabilis) grow best in cool, moist conditions. Select a site with shade or partial shade and moist, well drained organic rich soil.
These clump forming perennials generally flower early in the spring however, some varieties will flower longer than others. Generally, the cooler the location, the longer the blooms will last. After blooming has finished for the season leave the foliage in place. The leaves will gather sunlight, create food through photosynthesis and strengthen the plant.
