Start indoors 8-10 weeks before final spring frost. Sprinkle seed on soil surface and cover lightly as light aids germination. Firm soil and water gently. Transplant outdoors after last spring frost in a sunny, well drained location. Alternatively, sow outside in the fall and germination will occur in spring. To use foliage in lotions or creams, cut just as flowers begin to form and hang to dry.
