Hamamelis x intermedia 'Arnolds Promise'

Arnold Promise Showy Witchhazel

Hamamelis × intermedia ‘Arnold Promise’ is a deciduous shrub valued for its bright, clear yellow winter flowers and dependable performance. Oval green leaves emerge in spring, form a full canopy through summer, and turn shades of yellow to orange in fall, while clusters of narrow, ribbon-like golden-yellow flowers appear in late winter to early spring on bare branches, often with a light fragrance. Its vibrant color and reliable bloom make it one of the best-known witch hazels.
