Sinofranchetia chinensis

Sinofranchetia chinensis is a woody vine in the Lardizabalaceae family. It comes from central and southern China, including western forest regions. It grows in a temperate climate and sheds its leaves. Wild plants grow in woods, along valleys, and at forest edges. They also grow among shrubs at higher elevations. Their stems climb trees or spread through nearby shrubs.

This fast-growing vine reaches 30–50 feet (9.1–15.2 metres) in cultivation. Its spread can reach about 20 feet (6.1 metres). The stems twine around supports and have purple spots. Long leaf stalks hold three leaflets in a palmate pattern. The middle leaflet is larger than the two side leaflets. It has a broad, somewhat diamond-like shape with a narrower base. The side leaflets are oval. Each leaf has a thin, papery feel. The upper surface is dark green; the underside is gray-green.

Small flowers hang in long clusters from the stems. The clusters reach about 0.7–1 foot (0.2–0.3 metres) long. Male and female flowers are separate. Missouri Botanical Garden describes white flowers from May through July. Chicago Botanic Garden lists purple blooms from March through June. These sources differ on both flower color and season. The flowers and fruit add interest to the garden. The fruit is about the size of a grape. Plants For A Future lists it as edible raw. It also notes that the fruit has little flavor.

Grow this vine in sun or partial shade. In hot summer regions, some afternoon shade suits it best. It prefers soil with humus and a moderate supply of nutrients. The soil should stay moist but drain well. Choose a site with shelter from strong winds. Established plants can cope with some drought. Chicago Botanic Garden lists it for USDA zones 6–9. Seeds, cuttings, and summer layering offer ways to grow new plants.

Use this vine on an arbor, trellis, or wall support. It can also spread over large shrubs in woodland gardens. Allow room for its long stems and broad spread. Missouri Botanical Garden rates its upkeep as low. It reports no major pest or disease issues. Plants For A Future reports no known hazards or medicinal uses. That source also does not flag it as weedy.
