UT Gardens’ January 2023 Plant of the Month

KNOXVILLE, Tenn. – We all want something to look at in our gardens year-round. Blooms at unexpected times can bring a world of joy to the garden, and among the plants that offer them are witchhazels (Hamamelis spp.). There are many types of witchhazel shrubs and trees you can grow. Each one is a cool season favorite with fringed, often sweetly fragrant blooms. Many species also have nicely colored fall foliage adding to their appeal. 

Ranging in both habit and size, witchhazels vary in form from a dense rounded to a wide spreading shrub, or as upright multi-stemmed vase-shaped tree. While best grown in moist, well-drained, acidic soils, witchhazel is adaptable and tolerant of heavy clay. Plants can be grown in sun or shade, but increased sunlight with adequate moisture improves their flower display.

Witchhazel has low maintenance demands as well as good pest and disease resistance. Pruning is not required, but can be done in spring after flowering to control shape, size, and removal of any suckers from the rot stock. Although serious disease and insect problems are rare, Japanese beetles, leaf gall aphids, and powdery mildew can occur on occasion.

There are plenty of places witchhazel can fit in the home garden.  Plant as a single specimen, add to a mixed border or use in group plantings.  Overall, this is an easy and worthwhile plant to add to your landscape.

The following is a list of the more common species and hybrids and recommended cultivars. Most grow between 10- and 15-feet high and thrive in USDA Plant Hardiness Zones 5 to 8. Witchhazels can be found growing in all three locations of the University of Tennessee Gardens.

H. virginiana (common witchhazel): A fall blooming favorite among native plant lovers.

Grows 20 to 30 feet in the wild with cultivars in the 10- to 15-foot range. Fragrant, yellow blooms October to December. Golden fall foliage.

‘Harvest Moon’ – Notable for its tendency to drop its leaves before it flowers, unlike most other native varieties which flower with the leaves still attached making the blooms less visible.

‘Little Suzie’ – Compact, slow growing to 4 to 5 feet in 10 years. Blooms at an early age, more densely than the species.

H. vernalis (vernal/Ozark witchhazel) has the smallest flowers of all the species but makes up for size with the most intense fragrance. Grows 6- to 10-feet tall with wider spread. Yellow to red blooms January to March. New leaves emerge bronze to reddish purple with golden fall foliage.

‘Amethyst’ – deep red purple flower best backed by some lighter color.

‘Quasimodo’ – Dwarf, growing slowly to 4 to 6 feet. Fragrant, orange blooms. Leaves smaller than species, blue-green turning yellow in fall.
