Hamamelis x intermedia ‘Arnold Promise’ is a medium sized, 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 yellow/ orange/ red in autumn. Its yellow flowers appear in clusters.

Hamamelis x intermedia ‘Arnold Promise’ is commonly known as the Hybrid Witch Hazel Arnold Promise. The species is a hybrid between Hamamelis mollis and Hamamelis japonica. 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.

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 meaning ‘between’ and medius meaning ‘middle’ in reference to this hybrid being between its two parents in terms of characteristics.

The landscape architect may find Hamamelis x intermedia ‘Arnold Promise’ useful in dappled shade locations as a small tree with attractive, mildly fragrant winter flowers and autumn leaf colour.
