Large Fothergilla Mountain Witchalder

Large fothergilla is the bigger sibling, six to ten feet tall instead of three to five, with the same honey-scented white bottlebrush flowers in spring and the same incandescent fall color in orange, scarlet, and yellow. Native to the Allegheny Mountains from North Carolina and Tennessee northward, it develops a more open, upright form than the dwarf species, giving it a different landscape presence. The flowers appear in April to May before the leaves, standing out against the bare branches.

Large fothergilla shares the cultural requirements of its dwarf relative: acidic soil, consistent moisture, full sun to part shade. It is rated Zone 4a through 8b, so cold is never a concern. One disease is tracked, no significant pest pressure. In Western Washington, it works as a specimen shrub, a woodland-edge planting, or a backdrop for lower-growing companions. The fall color is as reliable as the dwarf form's and carries more visual weight because of the larger plant size. If you want the fothergilla experience on a bigger scale, perhaps behind a planting of dwarf fothergilla for a layered effect, this is the one.
