Rose of Sharon 'Bicolor': Hardy Hibiscus with Two-Tone Blooms

The Rose of Sharon 'Bicolor' (Hibiscus syriacus 'Bicolor'), also known as 'Lady Stanley' or 'Elegantissimus', is a classic, cold-hardy shrub that brings late-summer elegance to temperate gardens. Unlike its tropical cousins, this deciduous shrub withstands freezing winters and blooms prolifically from mid-summer into fall.

Distinctive Two-Tone Flowers

The single flowers are 3-4 inches across, featuring a striking bicolor pattern: pure white petals with a bold, central splash of deep red or burgundy that radiates outward like a star. The contrast is crisp and eye-catching. The shrub has an upright, vase-shaped habit, reaching 8-12 feet tall and 6-10 feet wide at maturity.

Hardy and Adaptable

'Bicolor' is hardy to USDA Zone 5. It thrives in full sun to part shade and adapts to a wide range of soils, provided they are well-drained. It blooms on new wood, so prune in late winter or early spring to shape and encourage vigorous flowering shoots. Drought tolerant once established. A low-maintenance star for the late-season garden.
