Rose of Sharon 'Diana', Shrub Althea 'Diana'
Noted for its prolific flower production and long blooming season, award-winning Hibiscus syriacus ‘Diana’ (Rose of Sharon) is a bushy deciduous shrub with elegant, saucer-shaped, pure white flowers, up to 5 in. across (12 cm), with slightly wavy petal edges. Unlike most hardy Hibiscus, they remain open into the evening. Blooming continuously from midsummer to frost, each flower lasts about one day. They stand out against the green foliage of broadly ovate leaves that turns golden-yellow in fall. A hardy, versatile and undemanding shrub, lasting for years without much effort, and ideal to brighten any garden.
