Deciduous broadleaf Winter blooms |
Spike winterhazel is a rare shrub from Japan and Taiwan. It is especially popular among hobbyists and garden enthusiasts.
Its small, primrose yellow flowers are born in 10-15 cm long, pendent racemes from early March until end April, weather conditions pending. They are fragrant and do not mind light frosts or snow. The shrub is usually literally flooded with flowers bare branches every year. It has more flowers in one raceme compared to corylopsis pauciflora and more erect branches.
Deciduous leaves are ovate, upto 10 cm across, bronze when young, bright to dark green in summer and rich golden-yellow in autumn. The only resemblance to hazels is the shape of leaves. Otherwise it has nothing to do with nut-hazels as it belongs to another family (hamamelidaceae – witch hazels). They need no pruning. If some trimming required, do so immediately after flowering.
It grows slowly to an open bush, 2m tall and wide. The best soil type is acidic, moist and moderately fertile. Plant it in filtered sun or partial shade. Avoid windy locations and frost pockets. Hardy to about -27°C (USDA zone 5).
