Sow directly in well drained garden soil in late spring after night temps are above 10C. Seeds can be started indoors 6-7 weeks before planting out, transplanting when 2″ tall. Scatter tiny seeds thinly, cover with fine soil and keep evenly moist. Transplant or thin so clusters of 3-5 seedlings are 6″ apart and plants will form mounds. When plants are well-established, cut sprigs of leaves.
