Diana Rose of Sharon-Hibiscus syriacus ‘Diana’

Large, pure white flowers will bloom abundantly and nearly continuously from summer until frost, with little to no seed production. Handsome, dark green leaves and a dense, compact growth habit are ideal for an informal hedge or screen. Highly tolerant to air pollution and drought. Deciduous. Hibiscus syriacus, commonly called rose of Sharon or shrub althea, is a vigorous, upright, vase-shaped, multi-stemmed, deciduous shrub that typically grows 8-12’ tall. It may be trained as a small tree or espalier. Showy, hollyhock-like, 5-petaled flowers (to 3” diameter) appear over a long, early-summer to fall bloom period. Each flower has a prominent and showy center staminal column. Palmately-veined, coarsely-toothed, three-lobed, medium green leaves (to 4” long) are attractive during the growing season but produce no fall color.

Description

Easily grown in average, medium moisture, well-drained soils in full sun to part shade. Best flowering occurs in full sun. Prefers moist, organically rich soils, but tolerates poor soils and some drought. Very tolerant of summer heat and humidity. Generally tolerant of urban conditions. Prune to shape in spring. Pruning back to 2-3 buds in late winter may produce larger blooms. Easily propagated by stem cuttings. May be grown from seed, but seedlings may not have the exact same flower color as the parent. Species plants can self-seed aggressively in optimum growing conditions.

Easy Care and Design Tips:
Finding the perfect planting spot where Althea will give you her best performance is easy as 1-2-3: 1) full sun, 2) well-drained soil and 3) an early-spring application of a slow-release fertilizer. This well-mannered plant is equally at ease as a landscape specimen or container plant. You’ll have to keep container plants watered more often, but the extra effort is worth it if you want to make an impact statement — plant Althea shrubs in matching urns on either side of your home’s sunny entrance for a glorious show of color all summer long!
