[edit] Description
It is a low, creeping, woody shrub to about 1 m tall and 1–2 m wide but often smaller. The green, ovate leaves grow in opposite pairs. The solitary flowers are 3–5 cm in diameter, a rich yellow, with five petals and numerous yellow stamens. It is indigenous to southeast Europe and southwest Asia.

In North America the name Rose of Sharon is applied to a species in a different order, Hibiscus syriacus.
