When to plant Spike Speedwell
Spike speedwell is a clumping perennial set out as a plant. Plant in spring once the soil is workable in full sun and moist, well-drained soil; NC State notes shearing back to the basal rosette after the late-spring-to-midsummer bloom can bring repeat fall flowers.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
