Witch Hazel
Hamamelis · Hamamelidaceae
Witch hazel flowers when nothing else does: between December and March, clusters of thread-like blooms in yellow, orange or red unfurl on the bare branches and shrug off even hard frost — in the cold the flower threads simply curl up and unroll again. Add a fine fragrance and glowing autumn colour. It grows slowly and wants to be planted with forethought, but rewards you for decades.

The key garden cultivars belong to Hamamelis intermedia: „Arnold Promise“ flowers late in bright yellow, „Jelena“ copper-orange, „Diane“ dark red and „Pallida“ early, sulphur yellow and strongly scented. A rule of thumb for long-range effect: yellow cultivars carry furthest in the winter garden, while red ones need a light background or they visually disappear against dark shrubs.
The position wants careful choosing, because witch hazel is a deep-rooted plant with fleshy roots and copes very badly with being moved when older. Ideal is a sheltered, sunny to semi-shaded solo spot — preferably somewhere you pass in winter, such as by the front door. The soil should be deep, humus-rich, fresh and slightly acidic to neutral; heavy, compacted or waterlogged soil is the most common reason for sulking.
Patience is part of the deal: witch hazels grow exceptionally slowly at ten to twenty centimetres a year and only reach their full size of two to four metres after many years. That is exactly why pruning is avoided — every cut costs flowering wood, and the picturesque funnel-shaped crown regenerates only reluctantly. At most, remove individual awkward shoots straight after flowering.
Ecologically the winter bloom is a gift: on mild days, bees and other early-active insects visit the nectar-rich flowers when there is hardly any other food. Combined with hellebores, winter heath and early bulbs, you get a winter bed that has something to offer continuously from December to March.
For the vase, witch hazel branches are a winter pleasure to be enjoyed with restraint: a few sparingly cut stems open their buds in a cool room and give off their fine scent. Because every cut stays with this slow-growing plant for a long time, we cut only cautiously — or fall back on branch material from the auction.

Witch hazel is considered non-toxic to cats, dogs and children — extracts of bark and leaves (hamamelis) are even used in cosmetics and skin care. Eating plant parts is still not advised because of the tannins they contain.
Overview: toxic & non-toxic plants for cats, dogs and children
Care
- 01Choose a sheltered, sunny to semi-shaded solo spot — visible from the house.
- 02Prepare deep, humus-rich, fresh soil; improve heavy soil with compost and sand.
- 03Strictly avoid waterlogging, but also summer drought — water in dry spells.
- 04Mulch the root zone and disturb it as little as possible; the fleshy roots are sensitive.
- 05Prune as little as possible; if necessary, straight after flowering.
- 06Choose the position for good — older witch hazels can hardly be transplanted.
Frequently asked
- When does witch hazel flower?
- The garden cultivars of Hamamelis intermedia flower between December and March depending on cultivar and weather, peaking mostly in January and February. The North American Hamamelis virginiana, by contrast, blooms in autumn. Frost does not harm the flowers — the thread-like petals curl up in the cold and unroll again.
- Why is my witch hazel not flowering?
- It usually comes down to soil or age: young plants need a few years before their first rich bloom, and compacted, waterlogged or parched soils make the plant sulk. A recent transplant shock or radical prune also costs several flowering years. Improve the site, mulch, be patient — witch hazels forgive slowly, but they do forgive.
- Is witch hazel toxic to dogs or cats?
- No, Hamamelis is considered non-toxic to dogs, cats and people. Proven skin-care extracts are even made from its bark and leaves. As a winter shrub for family gardens with pets, witch hazel is one of the safest options.
- Do you need to prune witch hazel?
- No — and it is best left alone. Witch hazel grows very slowly, builds its picturesque crown by itself and regenerates only reluctantly after cutting; every cut also removes future flowering wood. Only take out awkward or diseased shoots straight after flowering.
