Sowing Candytuft Seeds on an Embankment in Central NC

Candytuft (Iberis sempervirens) is perfect for slopes. In central NC (zone 7b), sow seeds directly outdoors 3 weeks after last frost (mid-April). Scatter 800 seeds over prepared, weed-free soil; press lightly; keep moist until germination. They’ll form a dense, evergreen mat with white spring flowers in 2–3 years. No need to start indoors.
