In the spring, lightly prune any leggy stalks to shape them. In the winter, lightly mulch any plants that are not in a pond. Plant seeds in the early spring at a depth of ¼ inch; if kept moist, they will grow into plants that bloom their first year. The clump can be divided in the late winter and planted 2 to 3 feet apart with the crowns 3 to 4 inches below the soil.

How to Plant Texas Star Hibiscus Seeds

Hardy hibiscus seedlings like the Texas Star will require cold stratification, which deceives seeds into entering a dormant state that is necessary for germination.

Alternatively, store dry seeds in the fridge for 60 to 90 days in a container or package that is tightly sealed.
