Common Name(s): Japanese Bleeding Heart, Common Bleeding Heart
Growing
On
From seed: Seedlings emerging in the winter or spring will
require up to a year before they fill out a gallon container.
It will take one full summer to develop a plant large enough
to produce blooms the following spring.
Commercial propagators have bare-root divisions available
during late fall and winter. Many times these are already
precooled so the roots can be planted to produce flowering
pot plants for the winter and early spring holidays or potted
up during mid to late winter for spring perennial plant sales.
The roots are potted up into 3- or 4- quart containers and
grown on at 50F to 55F (10C to 13C) nights. Dicentra spectabilis
will develop quickly, and February or March potted roots will
yield flowering plants in five to seven weeks. If grown under
cooler night temperatures or under prolonged, cloudy springs,
the plants will require up to one to two weeks longer to flower.
The crop time for a flowering pot plant for an early Easter
or for Valentine’s Day is from six to seven weeks at
50F to 55F (10C to 13C) nights. For plants that are to flower
during winter and early spring, research by Thomas Weiler
and Pamela K. Markham suggests that a 1,250 to 2,500 ppm B-Nine
application is effective when applied early. They suggest
that the ideal time is when “…the emerging sprout(s)
begin to unfold, 10 to 19 days after planting at 50F to 55F
night temperature(s).
