Editor's Note

Some resources note that all parts of Dicentra is poisonous if ingested. Symptoms include trembling, staggering, vomiting, diarrhea, convulsions, and labored breathing.

Reports of skin irritation and dermatitis have been reported after repeated contact with the cell sap.

The toxic principal is several isoquinolone alkaloids.

We tend to err on the side of caution in PlantFiles, and the danger notation in the details above is to warn gardeners, parents and pet owners to look further for more information.

A beautiful little mini bleeding heart, a bit of a diva in cultivation. Must have excellent winter drainage, full sun in AM to part shade in PM planted in a scree with humus to provide adequate moisture in the root zone. The seeds must be sown immediatly after harvest or stored in the fridge in slightly moist vermiculite for no more than 6 months. No dry storage. Germinates in warm-cold-warm pattern(68F-40F-55F, up to 2 years for germination. Can also be divided in late fall or early spring, while dormant. For the more experienced gardener, not an easy plant, but so satisfying to see it come back each spring.
