Hibiscus syriacus is a species of flowering plant in the family Malvaceae, native to India and much of Asia (though not, as Linnaeus thought, Syria, in spite of the name he gave it). Common names include rose of Sharon (especially in North America), Syrian ketmia or rose mallow (United Kingdom) and St Joseph's rod (Italy).
Hibiscus syriacus is a hardy deciduous shrub. It is upright and vase-shaped, reaching 2–4 m (7–13 ft) in height, bearing large trumpet-shaped flowers with prominent yellow-tipped white stamens. The flowers are often pink in color, but can also be dark pink (almost purple), light pink or white. Individual flowers are short-lived, lasting only a day. However, numerous buds are produced on the shrub's new growth, and this provides prolific flowering over a long summer blooming period. The soil in which the Hibiscus thrives on is a moist, but well-drained, mixture of sand, clay, chalk, and loam. Maintaining an Alkaline, Neutral pH(5.5 - 7.0) levels. Individual flowers that grow only last a day, contrasting when numerous flowers are produced providing a prolific life span lasting a long summer blooming period. They're highly tolerant to air pollution, heat, humidity, poor soil and drought.Shoots make interesting indoor vase cuttings, as they stay green for a long time, and some new flowers may open from the more mature buds. The species has naturalized very well in many suburban areas, and might even be termed slightly invasive, so frequently does it seed around.
The twigs are thin and gray, white-lenticeled, with raised leaf scars and small buds. Stems and branches do not branch very much unless pruned, resulting in many long, straight stems that originate from about 0.5-1.5' above the ground that give rise to the overall vased shape
