'Diana' Rose of Sharon (Hibiscus syriacus 'Diana')
hy-BIS-kus seer-ee-AY-kus
Genus:  Hibiscus
'Diana' has deep green foliage and large, pure white flowers that bloom from mid- to late summer. Unlike some other roses of Sharon, its flowers remain open at night. It requires little maintenance and, once established, will tolerate extreme heat, drought, and poor soil. -Judith Ireland, Regional Reports: Northeast, Fine Gardening issue #122
Noteworthy Characteristics:  As a mature shrub, this plant can be trained into a small tree.
Care:  This plant's flowers bloom on new growth, so you should prune it at the end of winter.
Propagation:  From cuttings.
Problems:  Leaf spots, Japanese beetles, blight, rust, aphids, scale, whiteflies, and canker.
