Fothergilla

A long lived forest understory plant in the wild; the Fothergilla grows well in partial shade though it can also grow well in full sun where its autumn leaf color is more intense if it is not subjected to drought. It prefers moist, rich, light, well drained soils though can generally be grown on just about any soil that can support an Azalea. Can tolerate spring flooding however root diseases can be a problem in the south on heavier soils. Other than that, the Fothergilla is almost entirely free of pest or diseases. Thought not native to the Northeast U.S. & Midwest, it grows exceptionally well ( except on unamended Midwest alkaline clays ) there and should be planted ALOT more! I give this plant a 10 / 10 for sheer beauty and multi season interest!
Propagation is from seed sown fresh, layering or softwood cuttings taken in summer.
Fothergillas do not like being transplanted however I have had alot of success and quick establishment with 1, 2 or 3 gallon size container plants. Never actually seen it sold ball and burlap and I wouldn't try it anyway. Transplanting is best in early spring before growth and second best in the fall or in winter in the Deep South.
Most Fothergillas are hardy to temperatures as low as -30 F, like many Southern U.S. plants they're natural range was pushed back by the previous ice age and they still retain their adaptation for northerly climates. The Fothergilla's foliage remains green late into autumn when it finally turns into an intense festival of color.
The flowers attract butterflies and hummingbirds, Fothergilla is not eaten by deer.




Fothergilla gardenii
The smaller of the 2 Fothergillas; this one is native to the southeast U.S. ( from Tennessee to North Carolina; south to Alabama to the Florida panhandle ). It is endangered in the wild, where it is usually found on deep sandy or peaty soils along the edges of wet longleaf pine savannas.
Generally reaching around 3 to 4 feet in height, with ideal growing conditions it can become much larger with great age. The largest on record is 10 x 9 feet. Generally slow to moderately growing, the maximum growth rate is 2 feet or 5.5 feet in height in 7 years.
The oval leaves are irregularly toothed and up to 4 x 2.5 inches in size. The foliage is deep green.
The white bottlebrush flowers are slightly honey scented fragrant and last up to 4 weeks appearing early in the spring before the leaves.
A great foundation plant never needing pruning.
Easy to grow and hardy zones 4 to 8.

'Mt Airy' ( Mt. Airy Fothergilla )
A medium-sized shrub that can reach up to 5 x 5 feet in 10 years, 7 x 7 feet in 15 years and with great age up to 8 x 8 feet ( record height is 10 feet ). More vigorous than Fothergilla gardenii - growth rates as much as 4 feet have been recorded under ideal conditions. Recently a new cultivar has come on the market called 'Alice' that is similar to 'Mt Airy' but has even more intense fall color.
Its leaves are also larger, up to 6 x 5 inches in size. The very attractive luxuriant dark green summer foliage turns to yellow, orange and red during autumn often with all colors on the same plant.
The flower buds are hardy down to -25 F and in bloom the white bottlebrush flowers are spectacular against a darker background such as evergreens.

  1. I have a new gardenii (planted in June). I live in southern NJ. We had 3 prolonged heat waves after it was planted, but I kept it watered and it has survived. But it lost a number of leaves -- they just shriveled up. And a lot of the remaining leaves have black spots, sometimes taking up half the leaf, sometimes multiple and small. The newest growth doesn't seem to have very many black spots. What is causing this? Is it a disease? We have a chipmunk problem -- could they be causing it? The soil is loose and well-mulched.
