Loropetalum is a small genus of evergreen shrubs and small trees in the witch-hazel family, Hamamelidaceae, within the order Saxifragales. It contains four recognized species, all native to East and South-East Asia, with distribution spanning China, Japan, and neighboring regions.
The genus is closely related to witch-hazel (Hamamelis), and shares its family's characteristic flowers: produced in clusters during spring, each bloom carries four to six slender, strap-shaped petals measuring 1–2 cm in length. This petal form gives the genus its name, derived from the Greek loron (strap) and petalon (petal). Species range considerably in stature, from compact shrubs under 2 m tall to small trees reaching 12–13 m.
The best-known member is Loropetalum chinense, which occurs in both a white-flowered wild form and a widely cultivated pink-to-crimson-flowered form. Other species include L. flavum (yellow flowers), L. lanceum (white flowers, tall tree habit), and L. subcordatum. Taxonomically, the genus is placed in tribe Loropetaleae, subfamily Hamamelidoideae.
