TO START INDOORS
Sow seed in early spring in a container of seed starting mix. Press gently into mix, but do not cover. Provide a good light source. Keep evenly moist as seedlings slowly emerge in 10 to 21 days. When seedlings are large enough to handle, acclimate gradually to outdoor conditions. Transplant clusters of 3 to 5 seedlings 8 to 10 in. apart in full sun.
TO PLANT DIRECTLY IN THE GARDEN
When warm spring weather arrives, sow in full sun in a well-worked, finely textured soil with good drainage. Sow seed as thinly as possible, but do not cover as seeds need light to germinate. Tend carefully, keeping seedbed evenly moist and well weeded.
Mix tiny seed with dry sand to help space seedlings. Young plants grow slowly at first; a good hot spell encourages strong growth. Pick leaves lightly the first season; wait until the second summer to make bigger harvests. Keep white blossoms cut off for best leafy growth. Given good drainage, this carefree Mediterranean native is hardy and long-lived.
