Aquilegia x caerula
25 Seeds | We think that no garden should be without this gem. Double-flowered golden blooms are breathtaking. They are shown in the traditional "spurred" form that gives Columbine its botanical name of Aquilegia. The spurs extend a full 2 inches beyond the blooms, sized just right for a hummingbird's beak and unlike any other flower shape in the garden. Winner of the 2010 Fleuroselect Novelty Award in Europe, this plant reaches about 2 feet high and 12 to 15 inches wide, with finely divided, feathery foliage that keeps it attractive even after the flowers pass.
Collected seeds produced from hybrid plants may not hold true in form to their parents.USDA Zone 3-9. Height 24-36 inches .
How to Plant Columbine Seeds
Sow seed and press into soil, however do not cover as light is needed to germinate.
- Columbine germinates best with stratification, a process of subjecting seeds to moist/cold treatment to break the seeds' dormancy. To stratify, sow seeds into moistened soil and place the container in plastic bag in the refrigerator or freezer for about 3 weeks. Seeds can then be taken out and germinated outdoors, in a sunny window, or under grow lights. Columbine also requires light to germinate. Be sure to simply press seeds into soil surface (instead of covering with soil.) The process described above should give you the best results, but note that your Columbine seeds may germinate fine without the stratification treatment.
Germination will take 21-29 days, Keep at 67-71° F.
You can direct sow Columbines, with 3-5 seeds per sow spot, space 6-20 inches apart, thin when 3-4 true leaves are present and leave the strongest seedling.
