  Previous topic Next topic JavaScript is required for the print function  

The genus Hamamelis is composed of six species native to North America [3] and temperate east Asia [3]. The word hamamelis is the classical Greek name of Mesipilus germanica L., medlar, or perhaps Sorbus domestica L., servicetree, words meaning together (in a time sense) and apple, which suggests flowers blooming at the same time.

Other Common Names: common witch hazel, snapping hazel, southern witch hazel, spotted alder, winter bloom.

Distribution: North America, from Nova Scotia, New Brunswick, Maine and Quebec, west to Ontario, Michigan and Minnesota, south to Iowa, Arkansas, Oklahoma and Texas, and east to Florida.

The Tree: Witch hazel is a fall-to-winter flowering tree or shrub. It has a thin, scaly, light- brown bark and small branches that grow in a zigzag manner. The flowers are bisexual with prominent, yellow, ribbon-like petals. The fruits are small, paired and horned. The tree at­tains heights of 30 ft (9 m) and diameters of 1 ft (0.3 m). Witch hazel grows at forest edges and along streams as an understory species. It grows best in deep, rich soils.

General Wood Characteristics: The sapwood of witch hazel is light brown, with a pinkish hue, while the heartwood is dark brown. The wood has medium luster and no odor or taste. It has medium density, fine texture, and straight grain.

The following description is for American holly.

Distribution: North America, from Massachusetts, Connecticut and New York, southwest to Pennsylvania, West Virginia, Ohio, Kentucky, Missouri and Oklahoma, south to Texas and east to Florida.

The Tree: Hollies have spiny evergreen leaves and red berries on the female trees. Holly is found in lower areas of deep, rich, moist soils in association with magnolia, oaks, sweet gum, maples, and hackberry. It reaches a height of 50 ft (15 m) with a 2 ft (0.6 m) diameter. The bark is thick and relatively smooth with rough wart-like processes.

General Wood Characteristics: The sapwood of holly is white and the heartwood is an ivory white with a bluish cast or streaks. The wood has no characteristic odor or taste. It is heavy, hard, close-grained and tough, with a low luster like ivory.
