Hardy Yellow Hibiscus Hibiscus hamabo

Other Common Name(s):

Phonetic Spelling
hy-BIS-kus ham-AY-boh
Description

Hamabo hibiscus is a small, broadleaf evergreen tree or large shrub native to China, Korea, and Japan and in the Malvaceae (mallow) family. It grows 6 to 15 feet in height and 10 to 15 feet wide and has flowers that last from mid-spring through the first frost.   

Plant in full sun to partial shade and in an area with good drainage. Prune to maintain a dense habit. Flowers appear on new growth from late spring to mid-fall, with blooms turning orange as they age. The flowers are attractive to hummingbirds, pollinators, and butterflies. It is more cold tolerant than other hibiscus, and like Hibiscus rosa-sinensis is resistant to salt, and drought tolerant once established.

Its small stature works as flowering tree for a courtyard or patio gardens.  Its showy flowers, which have a mild fragrance, bring light and interest to a cottage garden.  Plant Hamabo hibiscus in small groups in the middle or back of a border planting, or use as a hedge or screen.  Their salt tolerance makes them a good choice for a coastal location.  In cooler climates, they do well planted in large containers where they can be brought inside over the winter. This plant is susceptible to damage from deer. 

Insects, Diseases, or Other Plant Problems:  It has some susceptibility to blight, canker, rust, leaf spots, aphids, scale, whiteflies, and Japanese beetle. Taller plants may need staking.  Moth larvae can bore into the fruit.
