When to plant Lambs Ear
Lambs ear is a low, spreading groundcover perennial set out as a plant and propagated by division. Plant in spring once the soil is workable in full sun and well-drained soil; NC State notes it may need dividing every two to four years and that wet leaves invite disease.
The calendar shows this cited seasonal window as an approximate band. It does not convert the season into frost-adjusted dates.
