HEIRLOOM Exquisitely elegant and impressively tenacious, we swoon all summer over larkspur’s ivory double-blooms with glorious chartreuse margins. Often 3+ feet tall, spires of blossoms stack on strong stems perfect for cutting as hummingbirds and butterflies flock to our larkspur.
For fresh arrangements, harvest when one-third of the flowers on the stem are open, starting at the bottom. For dry arrangements, harvest stems when three-quarters of the flowers are open and before petals begin to drop. Hang out of direct sunlight for two weeks to maintain its best, longest color.
All parts of Larkspur are poisonous when ingested by mammals, including the seeds, but you won’t have any trouble sowing and harvesting her blooms all summer long.

When to sow: early spring or late fall. Seeds do not germinate well when soil temperatures are above 55°F. Speed up germination by chilling seed in refrigerator or freezer for a week before sowing. Plants should ideally stay above freezing but below 55°F for the first six weeks of growth.
Direct Sow recommended. (To transplant, Sow 2 seeds per soil block, 4 weeks before final frost, thinning to one. Transplant with care to avoid disturbing the taproot.)
