| Hibiscus is either tropical (annual) or hardy (perennial). A hibiscus with glossy, deep green leaves and red, pink, orange, or yellow, double or single flowers is probably a tropical variety, which is an annual outdoors in cold weather climates. Hardy hibiscus will have dull, medium-green, heart-shaped leaves; dinner plate-size white, pink, or red flowers; and huge, bomb-shaped buds. |
