Hibiscus rosa-sinensis, commonly called Chinese hibiscus, is a frost tender evergreen that is probably native to tropical Asia. Plants feature glabrous, toothed, shiny green leaves (to 6â€) and large, funnel-like flowers (to 4-8†diameter) with stamens in a showy central tube. Plants grown outdoors year round typically rise to 10-12’ tall, and plants grown in containers that are overwintered indoors are typically trimmed to 5-6’ tall. Outdoor plants will flower throughout the year. Plants brought indoors in fall typically flower from spring to late summer. Flowers last for only one day. Indoor plants need regular pruning to maintain good shape. Another common name for plants of this species is rose of China. Genus name is the old Greek and Latin name for mallow.
