- History & LoreHistory:The ancestors of this modern hybrid are both from Asia. One parent is the highly variable H. japonica, collected and classified by Von Siebold and introduced by the English nursery firm of Vietch and Sons. The other parent, H. mollis, is native to China and collected by Charles Maries in the district of Kukiang in 1879 while working for Veitch. The plant was not officially classified as x Hamamelis until the turn of the century when this new line of Asian witch hazels, not the native Hamamelis, were brought into American Gardens. 'Arnold Promise' was developed at the Harvard University Arnold Arboretum where it was introduced in 1928.
