Witch-hazel

Witch-hazel, is the common name for a genus of shrubs Hamamelis in the family Hamamelidaceae, with four species, two in North America (H. virginiana and H. vernalis), and one each in Japan (H. japonica) and China (H. mollis). The Perian ironwood, a closely related tree formerly treated as Hamamelis persica, is now usually given a genus of its own, as Parrotia persica. Other closely allied genera are Parrotiopsis, Fothergilla and Sycopsis (see under Hamamelidaceae).

They are popular garden shrubs, grown for their clusters of rich yellow to orange-red flowers which begin to expand in the autumn before the leaves fall and continue throughout the winter. The bark and leaves are astringent, the extract, also referred to as Witch Hazel, is used medicinally. The seeds contain a quantity of oil and are edible. The name is derived from the use of the twigs as divining rods, just as hazel twigs were used in England.
