Sowing
Direct-sow in early spring for summer bloom or in autumn for earlier bloom next year (Johnny's). It germinates best in cool soil, about 55°F.
Care and transplanting
Support tall spikes. Larkspur hates heat and root disturbance.
Problems
Seed fails in warm soil. Plants fade in summer heat.
Saving seed
Self-sows freely; collect dry pods.
