Overview

Hamamelis × intermedia is hybrid witch hazel (winterbloom), a spreading deciduous shrub growing 10-20 feet (3-6 m) tall and 10-15 feet (3-4.5 m) wide. Strap-shaped (ribbon-like) fragrant flowers with crinkled petals 0.5-0.75 inch (1.3-2 cm) in clusters along bare stems in January-March — color ranges from yellow through orange, copper, and red depending on cultivar. The petals curl inward during freezing temperatures and unfurl when temperatures rise. Medium to dark green oval leaves 3-5 inches (7-13 cm). Turns yellow, orange, and red in fall. In Hamamelidaceae. Hybrid of H. japonica × H. mollis. Popular cultivars: 'Arnold Promise' (clear yellow), 'Diane' (dark red), 'Jelena' (copper-orange), 'Pallida' (pale sulfur-yellow, strong fragrance). Requires acidic well-drained soil (pH 5.5-6.5) — iron chlorosis in alkaline conditions. This acid-soil requirement is the primary limitation. Not drought-tolerant. Grafted on H. virginiana rootstock — remove rootstock suckers promptly. Slow-growing. Deer-resistant. Non-toxic. Zones 5-8. Full sun to partial shade. Growth rate is slow.

Native Range

Hybrid of garden origin — H. japonica (Japan) × H. mollis (China). First raised at the Arnold Arboretum, USA.

Suggested Uses

Grown as a specimen shrub near entryways, paths, and windows where the late winter bloom and fragrance can be experienced, spaced 10-15 feet (3-4.5 m). Winter bloom on bare stems. Fragrant. Multicolor fall foliage. Requires acidic soil. Deer-resistant. Non-toxic. Zones 5-8.

How to Identify

Identified by strap-shaped (ribbon-like) fragrant flowers with crinkled petals in clusters along bare stems in late winter on a large spreading deciduous shrub. The strap-shaped petals and the winter bloom timing on bare stems are diagnostic for Hamamelis. Distinguished from H. virginiana (native witch hazel — blooms in fall, yellow only) by the winter bloom timing and the range of flower colors (yellow through red). In Hamamelidaceae.

Care & Maintenance

Care Guide

Full sun to partial shade (4-8 hours — full sun for densest bloom). Acidic well-drained soil pH 5.5-6.5 — iron chlorosis in alkaline conditions. Not drought-tolerant. Grafted on H. virginiana rootstock — remove rootstock suckers promptly (different leaf shape, fall bloom). Prune lightly after flowering if needed. Deer-resistant. Non-toxic. Zones 5-8.

Pruning

Prune lightly after flowering (March-April) if shaping is needed — blooms on old wood. Remove rootstock suckers (H. virginiana) at the base promptly — they bloom in fall with smaller yellow flowers and have different leaf shape. The spreading vase-shaped form is natural. Minimal pruning needed.
