Planting & Care

Sow Hardy Hibiscus seeds indoors 8–10 weeks before the last frost. For best results, cold stratify seeds by refrigerating them in a moist paper towel for 4–6 weeks before sowing. Press seeds lightly into the soil surface, as they need light to germinate. Maintain a temperature of 70–75°F and keep the medium consistently moist. Germination can take 2–4 weeks.

Once seedlings have several sets of true leaves, transplant them outdoors after the danger of frost has passed. Choose a location with full sun and moist, rich soil. Water regularly, especially during dry spells, as this plant does not tolerate drought well. Mulch around the base to retain moisture. In late winter or early spring, cut back old stems to encourage fresh growth. Hardy Hibiscus may be slow to emerge in spring, so be patient.
