Hibiscus ‘Black Dragon’ (Hibiscus rosa-sinensis hybrid) Flower Shrub， Blue Flowers Hardy Korean Rose of Sharon Starter 25+ seeds pack Starting Your Hardy Hibiscus from Seed Starting seed varieties at home is easy and fun and also an economical way to enjoy the plant from beginning to end. Sow seed indoors 6-12 weeks before the last frost depending on your zone. Seeds soaked overnight help jumpstart the process. Sow the large seed ½ inch deep into well-draining soil and keep at 60% humidity in full sun or under lamps. After 4-5 weeks， transplant into larger pots， taking care not to disrupt the taproot. As the last frost approaches in the spring， harden off the transplants during the day to achieve a stronger and more weather-resistant plant. Better branching and thus more flowers can be achieved by pinching back the tips when the young plant is around 6-8 inches in height.
