Coastal Witch-Alder
Fothergilla gardenii
Easy · Beginner friendlyAbout Coastal Witch-Alder
Dwarf Fothergilla is a compact deciduous native shrub of the southeastern US coastal plain, growing 2-3 feet tall with bottlebrush-like spikes of fragrant white flowers in early spring before the leaves emerge. The honey-scented flowers have no petals—the white display comes entirely from showy stamens. In autumn, the blue-green leaves transform into a kaleidoscope of yellow, orange, and scarlet, often with all colors present on a single leaf. A four-season gem native from Virginia to Alabama.

History
Fothergilla gardenii is native to the Atlantic and Gulf Coastal Plain of the southeastern United States from North Carolina south through Georgia and Florida and west to Alabama and Mississippi, typically in acidic pine flatwoods and shrub bogs. Linnaeus established the genus in 1774 to honor John Fothergill (1712-1780), the Quaker English physician and botanist who maintained one of the finest botanical collections in Europe at Upton in Essex. The species epithet gardenii honors Dr. Alexander Garden (1730-1791), a Scottish-American physician-naturalist in Charleston, South Carolina, who sent specimens to Linnaeus; the genus Gardenia is also named for him.
The dwarf fothergilla is a compact 0.6-1 meter shrub producing apetalous bottlebrush-like spikes of white stamen-dominated flowers in April before or with leaf emergence, followed by spectacular autumn foliage in combinations of scarlet, orange, yellow, and burgundy. Introduced to cultivation around 1765, it remained uncommon in gardens until its rediscovery by North American native-plant enthusiasts in the late 20th century.
'Mount Airy' (a probable F. x intermedia from Michael Dirr in 1993) is the most widely grown selection. The cultivar 'Mt. Airy' from the Mt. Airy Arboretum in Cincinnati is the gold standard, selected for its compact habit and blazing fall color. Related to witch hazels (Hamamelis) in the same family.
