Hamamelis x intermedia ‘Pallida’ is a deciduous spreading small tree or large shrub. The light green alternate leaves emerge from short-stalked buds. The leaves are elliptic to nearly circular in shape, irregularly toothed along their edges and become a coppery orange in autumn. The branches of this tree form a ‘V’ shape. The fragrant flowers are bourne in clusters of two to four. The large individual sulfur yellow petals are fragrant, strap like, slightly wavy and 25mm long, with the centres of the flowers being red/ purple. The fruits are small, hairy, brown, oval capsules. It is grafted onto the rootstock of one of the other species of Hamamelis.

The species Hamamelis x intermedia is commonly known as the Hybrid Witchhazel. It is a hybrid between Hamamelis mollis and Hamamelis japonica. This plant was introduced into the UK around 1932. Subjective research has been carried out on the relative fragrance and leaf retention of various Hamamelis species and varieties by the curators of  Scott Arboretum, unfortunately Hamamelis x intermedia ‘Pallida’ is not included on this list.

The etymological root of the binomial name Hamamelis is derived from the Greek amamelis ‘a tree with pear like fruits’. Intermedia is derived from the Latin inter ‘between’ and medius ‘middle’ in reference to this hybrid being between its two parents in terms of characteristics. Pallida is from the Latin meaning ‘pale/ yellow green’, referring to this varieties pale flowers.
