Growing instructions for Dicentra spectabilis – bleeding heart
Bleeding Heart seeds should be sown while they are fresh.
If your winter season includes 6-8 weeks of freezing weather, you can sow seeds of Dicentra spectabilis directly into your garden in the late fall.
The seeds will germinate during the following spring.
To start Bleeding Heart seeds indoors, sow fresh seeds in a
moistened growing medium, then freeze them for six weeks.
After the freezing period, move them to an area where you can maintain
a temperature in the growing medium of 55°-60° until germination,
which takes anywhere from 30-50 days.
