How to Grow
Larkspur germinates best in cool soil, so direct sow in fall or very early spring — it actually benefits from a cold spell. If germination is slow, chilling seed in the fridge for a week before sowing can help. Keep soil moist until seedlings emerge. Once established, larkspur needs little care; stake in windy spots given its height.
Good to Know
Larkspur is a true cool-season plant — sown in fall, it will overwinter as a small rosette and take off with dramatic height once spring warms up.
