Rose of Sharon
Hibiscus syriacus
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. Grows 7’-10’ and almost as wide. It may be trained as a small tree or espalier. Showy, hollyhock-like, 5-petaled flowers (up to 3” diameter) appear over a long, early-summer to fall bloom period. Hardy to zone 5.
