Annual

Hibiscus acetosella

Will overwinter in zones 8 and up or in a greenhouse or sunroom. Very easy to germinate. Start indoors 8-10 weeks before last spring frost. Germinate at 20°C (68°F), covering lightly. Transplant seedlings into larger containers as soon as they are large enough to handle. Early pinching of shoots will encourage bushiness. After danger of frost has passed, plant out, spacing 20 inches apart. May produce large funnel shaped burgundy flowers. Prefers full sun or light shade.

Hibiscus trionum

Start inside 10 weeks before last frost. Germination will take place in 14-21 days at 18-22°C. Grows to about 14 inches high. Space 10 inches apart in garden.
