Hamamelis intermedia 'Arnold Promise'
Hamamelis intermedia 'Arnold Promise' — Witch Hazel
Widely regarded as one of the very finest witch hazels ever raised, Hamamelis intermedia 'Arnold Promise' is a plant of exceptional winter beauty and enduring reputation. From late winter into early spring, its bare branches are wreathed in clusters of rich golden-yellow, ribbon-like flowers — each one intensely fragrant with a warm, spicy-sweet scent that carries through the cold garden air with remarkable presence. It is, quite simply, one of the most uplifting plants you can grow.
As the seasons turn, 'Arnold Promise' delivers a second outstanding performance: the broad, textured leaves colour brilliantly in autumn, turning through shades of gold, orange, and flame red before leaf fall — a display that rivals many trees for sheer impact.
