Botanical Name

HIBISCUS syriacus 'Helene'

Plant Common Name

Helene Rose-of-Sharon, Rose-of-Sharon

General Description

Vigorous and summer-blooming, the rose-of-Sharon 'Helene' has a dense, bushy upright habit and has some of the prettiest flowers. The blossoms of ‘Helen’ are large and especially showy with white petals marked with a ruby red eye that feathers out like a starburst. In the center is a tan-colored floral tube. The blooms offer a magnificent display from midsummer through autumn. The lobed green leaves of this deciduous shrub turn dirty yellow in fall.

Rose-of-Sharon grows best in full to partial sun and fertile loam with even moisture and good drainage. It is easy to grow and well-suited as an informal hedge or screen. ‘Helene makes a nice addition to mixed shrub borders or may be planted as landscape specimen.
