Fothergilla major, commonly known as Large Witch Alder or Mountain Witchalder, is a deciduous shrub native to the understory of deciduous forests, particularly in the Allegheny Mountains and southern Appalachian Mountains of the southeastern United States. It typically grows to a height of 6 to 10 feet (1.8 to 3 meters) and is equally wide. The plant features fragrant, white, bottlebrush-like flowers that bloom in spring, often appearing with or before the emergence of the glossy, blue-green leaves. The foliage is particularly noted for its spectacular autumn color, displaying vibrant shades of yellow, orange, and red.

Large Witch Alder is valued for its multi-season interest, including its showy flowers and brilliant fall foliage. It is used in garden landscapes as a specimen plant, in shrub borders, and for naturalistic plantings. This shrub is adaptable to a range of light conditions, from full sun to part shade, and prefers moist, well-drained, acidic soils. While it is somewhat drought-tolerant once established, consistent moisture will ensure the best growth and flowering. It is resistant to most pests and diseases, making it a low-maintenance choice for gardeners. Fothergilla major is hardy in USDA zones 4–8 and can be propagated by softwood cuttings or division.CC BY-SA 4.0
