Lonicera quinquelocularis

Lonicera quinquelocularis, or translucent honeysuckle, belongs to the honeysuckle family, Caprifoliaceae. Its native range runs from eastern Afghanistan to the Himalaya. It grows as a large shrub or small tree. This deciduous plant loses its leaves for winter. In the wild, it grows in woods, scrub and hedges. It also occurs on open hills and rather dry slopes. These habitats lie at 5,900–9,840 feet [1,800–3,000 metres] above sea level.

The plant has a bushy shape with spreading branches. The RHS gives a garden height range of 13–26 feet [4–8 metres]. Its shorter account describes plants reaching about 16 feet [5 metres]. Allow for a spread of 8–13 feet [2.5–4 metres]. It takes about 10–20 years to reach full size. Young stems have a purple tint and a thick coat of soft hairs. The green leaves are oval and hairy too.

Clusters of flowers appear in early summer. Each flower has two lips. The blooms open cream, then turn golden yellow as they age. Rounded or oval berries follow the flowers. Their white skins let light pass through, giving them a translucent look. These pale fruits are a key feature of this honeysuckle. They serve as garden ornament, not food. The RHS warns against people or pets eating them.

Grow this species in full sun or partial shade. Choose a sheltered site with moist soil that drains well. It accepts clay, chalk, loam and sand. Acid, neutral and alkaline soils all suit it. The RHS rates its hardiness H6, covering winter lows near −4°F [−20°C]. Plants For A Future lists USDA zones 4–8. Its suggested woodland settings include sunny edges and places with dappled shade. Gardeners can raise new plants from seed or several types of stem cuttings.

Its size and branching form can give structure to informal gardens. The RHS also suggests it for cottage and wildlife gardens. Aphids may attack it, and powdery mildew can affect it. Plants For A Future lists no known food or medicinal uses. Its lack of a hazard record does not override the RHS fruit warning. Wear gloves and other protective gear when handling it, as the RHS advises. The hard, fine-grained wood takes a smooth polish. Recorded uses include walking sticks and fuel. It also has potential for carving and lathe work.
