The Story
Plant Bio
Fothergilla major, the mountain witch alder, is a deciduous shrub native to mountain woods and ravines of the southeastern United States, growing six to ten feet high and five to nine across. It is a witch hazel relative, and its white bottlebrush flower spikes open in April and May before the leaves, carrying a honeyed scent. Autumn colour is intense.
The autumn display is its strongest asset, with yellow, orange and scarlet often appearing on the same leaf, and it is reliable rather than occasional. It needs acidic, organically rich soil to perform, which is why it pairs so naturally with rhododendrons: they want exactly the same ground and fail in the same conditions.

- Plant in autumn or spring in full sun to part shade.
- Choose moist, acidic, organically rich, well-drained soil.

Pro Tip
