Hibiscus Malvaceae | ||||
Description: Hibiscus syriacus or Rose-of -Sharon are tall growing, spreading shrubs. They are grown chiefly for their summer flowers that blume well into autumn. |
Flower: .Holly-hock like 2-4 inch flowers in purple, white, pink, blue, red, or in various color combinations. Three flower forms are available in hibiscus: single, semi-double, and double. Most cultivars have flowers with dark red centers of rose or rose-red, but a few have unmarked blooms. |
Foliage: Foliage is not outstanding and leaf bud do not unfold until late spring. Because of this, many gardeners are certain that their plants are dead. Patience usually will prove otherwise. |
