Dwarf fothergilla (F. gardenii) reaches only 2 to 3 feet tall while large fothergilla (F. major) can reach 6 to 10 feet. Hybrids between the two (F. × intermedia) typically grow 4 to 5 feet tall. All fothergillas bear short, upright, bottlebrush-like flower heads in spring.
Small individual flowers are creamy white and smell deliciously of honey. Fothergillas have oval to rounded leaves (smallest on dwarf fothergilla) that are light green to blue-green in summer and develop stunning shades of red, orange and yellow in late autumn. These tidy, mounded shrubs are ideal for formal or informal gardens, borders or foundation plantings.

All in the family
- Fothergillas are members of the witch hazel family (Hamamelidaceae), which contains about 100 shrub and tree species.
- In addition to the fothergillas, other choice ornamental shrubs in the family include witch hazels (Hamamelis), winter hazels (Corylopsis) and disanthus (Disanthus cercidifolius).
- The native sweetgum tree (Liquidambar styraciflu ) was previously considered a member of this family but has recently been reassigned.
