Give your garden or landscape a tropical look with hardy hibiscus plants. Also called Rose of Sharon, these low-maintenance perennials produce large, showy flowers and attractive foliage. Most hardy hibiscus plants bloom in mid to late summer and lure butterflies to the garden. Because they grow well in moist areas, they're a good choice for planting along the sunny edges of ponds, streams and other water features. Deer tend to pass them by. The shrub-like plants can also be grown in groups to form a flowering hedge. Most hardy hibiscus can be grown in zones 5-10. Hardy Hibiscus are available in an array of flower colors including red, pink, white and other hues.
