When to plant Annual Larkspur
Larkspur is a winter annual. The University of Arkansas directs sowing seed in September and October in southern gardens for spring bloom; in northern areas it blooms over summer. Scatter seed thinly in a fertile, uniformly moist bed.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
