Celastrus angulatus

Celastrus angulatus is a deciduous climbing shrub in the Celastraceae family. It comes from central and southern China, within temperate Asia. In the wild, it grows in mountain thickets and on slopes. These habitats lie at 3,280–8,200 feet [1,000–2,500 metres] above sea level. It is not native to Britain or Ireland. The name Celastrus latifolius is listed as a synonym.

This fast-growing climber reaches about 24 feet [7.3 metres] tall. Its spread can reach about 33 feet [10 metres]. It needs ample room rather than a small planting space. The stems twine around supports, while prickles on young stems also help it climb. An old tree can provide a suitable support. It loses its leaves each year. Routine pruning is not usually needed. Its strong growth makes space and support key parts of garden placement.

Flowers appear from July to August, and bees pollinate them. Male and female flowers grow on separate plants. Both sexes must be present to produce seed. Seeds ripen from November through February. The flesh around the seeds can hinder germination. Remove this flesh before sowing. Seed can be collected when ripe and kept in dry sand. Three months of cold treatment can improve germination. Young seedlings need greenhouse shelter through at least their first winter.

A deep loam rich in humus suits this plant best. It also grows in sand or clay if the soil has enough depth. It accepts mildly acid, neutral, and mildly alkaline ground. Keep the soil moist. It tolerates shade, though sun on the upper growth encourages more flowers. Woodland edges and sites with dappled shade suit its use in gardens. The source also records growth in full shade. Its listed USDA hardiness range is zones 4–8.

Propagation options include summer cuttings and layering the current year's shoots. Layering can take about a year to form roots. Plant young specimens outside after the last expected frost. No edible uses are recorded, and the source gives edibility a zero rating. It lists no known hazards, but this does not establish safety for eating. The plant has reported insecticidal uses. Its large size and vigorous climbing habit remain important limits in garden design.
