Fothergilla (witch alder) is a genus of two to four species of flowering plants in the family Hamamelidaceae, native to woodland and swamps of the southeastern United States. They are low-growing deciduous shrubs growing to 1 - 3 m tall with downy twigs. The brush-like flowers are produced before the leaves in spring on terminal spikes; they do not have any petals, but a conspicuous cluster of white stamens 2–3 cm long. The leaves are alternate, broad ovoid, 4–10 cm long and 3–8 cm broad, with a coarsely toothed margin; they are noted for their brilliant orange or red fall colors.

Species

Etymology

The genus was named in honor of the English physician and plant collector Dr. John Fothergill (1712-1780) of Stratford, Essex, who was known for introducing American plants to Britain.

Cultivation and uses

Fothergillas are grown as ornamental plants for their spring flowers and fall foliage color. They are slow-growing, rarely exceeding 1–2 m tall in cultivation. The hybrid cultivar Fothergilla × intermedia 'Mount Airy' has gained the Royal Horticultural Society's Award of Garden Merit.
