Depending on environmental conditions, these flowering stems are more or less erect, or they can sprawl across the ground. The stems are gray-green or gray-blue, and hairless. Arranged around each stem, there are dense whorls of small leaves. These leaves are up to 1½” long and less than ¼” across; they are linear-oblong, gray-green or gray-blue, smooth. The blooming period usually occurs during early to mid-summer. The short-lived flowers open during the early morning and close by noon. Culture: Sow, in early spring after last frost date for your area, in a well tilled soil, raked smooth. Choose a sunny location. Broadcast seed evenly and rake lightly into the soil. Regular watering is essential to establish plants. During growing season, spot weeding where needed.
