History
Leucothoe axillaris occurs naturally in the Atlantic and Gulf Coastal Plain of the southeastern United States from Virginia south through Florida and west to southeastern Louisiana, typically in acidic woodland streamheads, seepage slopes, and wet pine flatwoods. French botanist Jean-Baptiste Lamarck described it as Andromeda axillaris in 1783, and Scottish botanist David Don transferred it to the genus Leucothoe in 1834. The genus name honors Leucothoe, a figure in Greek mythology transformed into a flowering shrub by the god Apollo.
The 1-1.5 meter shrub features arching zigzag stems with glossy evergreen lanceolate leaves that often turn rich purple-red in winter. Small white urn-shaped flowers in leaf axils (hence axillaris) open in April-May, emitting a subtle sweet honey-lily fragrance. The species resembles the closely related and better-known L. fontanesiana of mountain regions but is smaller and more compact.
Modern cultivars include 'Little Flames', 'Scarletta' ('Zeblid'), 'Rainbow', and 'Girard's Rainbow' with variegated or highly colored new growth. Like its rhododendron relatives, all parts are toxic due to grayanotoxins. A Southern heritage plant long cultivated in Charleston and Savannah gardens, prized for evergreen texture in deep shade. Native American tribes used branches in ceremonies.
