Witch-hazel is a genus of flowering plants in the family Hamamelidaceae, with three species in North America (H. ovalis, H. virginiana and H. vernalis), and one each in Japan (H. japonica) and China (H. mollis).
They are deciduous shrubs or (rarely) small trees growing to 3-8 m tall, rarely to 12 m tall. The leaves are alternately arranged, oval, 4-16 cm long and 3-11 cm broad, with a smooth or wavy margin. The horticultural name means 'together with fruit;' its fruit, flowers, and next year's leaf buds all appear on the branch simultaneously, a rarity among trees.
