Description
Hibiscus syriacus is a hardy, deciduous shrub or small tree growing up to 8-12 feet tall with an upright and vase-shaped habit. It produces striking, showy flowers with prominent staminal columns, blooming profusely from mid-summer through autumn when many other shrubs have finished flowering

Native to temperate Asia (China, India, and parts of the Middle East), but widely cultivated and naturalized across North America and Europe
Condition Notes
