Research Reference Books



Although Maria’s reference library includes some very useful books about cut flower production, only a few provided any detailed information about Dicentra sp. as a cut flower. The following excerpts show the information provided in these books.

Growing 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).
