Latest analysis has confirmed 4 distinct species throughout the genus:

  • F. gardenii, dwarf or coastal fothergilla or witch alder
  • F. main, tall or mountain fothergilla or witch alder
  • F. milleri, dwarf witch alder
  • F. parvifolia, Kearney’s dwarf witch alder

The three dwarf species are so related that many horticulturists take into account them to be variations of F. gardenii and refer to those crops merely as “dwarf” or “giant” fothergilla.

F. gardenii and F. main are the 2 you’re more than likely to seek out when purchasing for shrubs.

Alabama fothergilla was beforehand categorised as a definite species, F. monticola, however it’s now thought-about to be F. main.

Dwarf species and cultivated varieties are greatest suited to Zones 5 to eight. They develop to mature dimensions of 18 to 36 inches tall and 24 to 48 inches vast.

Progress is compact and bushy, the flowers seem earlier than the foliage, and the leaves have symmetrical bases.

Giant sorts develop greatest in Zones 4 to eight, reaching six to 10 ft tall with a width of 5 to 9 ft.

They’ve an upright, spreading progress behavior, and bloom on the similar time the leaves emerge. The leaves are bigger than these of the dwarf species, and the bases are asymmetrical.

There are additionally hybrid varieties categorised as Fothergilla x intermedia.

Along with the species talked about, fossilized specimens of two US species, F. malloryi and F. praeolata, and others in China and Japan point out that the Fothergilla genus dates again tens of millions of years.

This means an environmental resilience probably chargeable for its exemplary pest and illness resistance, and desirability as a business and residential panorama shrub.

It could possibly take between 9 and 15 months for seeds to germinate.

Additionally, seeds from hybrids and different cultivated varieties might not be viable. If they’re, they received’t produce true replicas of the dad or mum crops.

To clone a favourite, take smooth stem or sucker cuttings.

Recut the stem slightly below the bottom leaf node, a pure rising level.

Dip the minimize finish into rooting hormone powder.

Place the stem in a four-inch seed starter pot crammed three-quarters stuffed with potting soil at a depth slightly below the bottom remaining leaf.

If there may be tip foliage along with the bottom leaf, pinch off the most recent progress on the tip.

Put the pot in vivid, oblique daylight and preserve the soil evenly moist however not waterlogged.

New leaves signify the profitable institution of roots and readiness for transplant.

From Softwood Stem Cuttings

To take a softwood stem chopping:

Lower a four-inch size of sentimental, inexperienced stem slightly below a leaf or leaf node. The stem needs to be lengthy sufficient that it has a number of leaf nodes.

Pinch or snip off the bottom leaf and the tip progress, then dip the minimize finish of the stem into rooting hormone powder.

Insert the dipped stem right into a four-inch seed starter pot three-quarters stuffed with potting medium to a depth slightly below the bottom leaf.

Moisten the soil and preserve it evenly moist throughout institution. Place the pot in vivid, oblique daylight.

When new progress seems, transplant the chopping to the backyard earlier than summer season’s finish to provide it time to ascertain earlier than the primary frost.
