Kadsura oblongifolia

Kadsura oblongifolia is a climbing shrub. It belongs to the Schisandraceae family. Its stems twine as it climbs. It is evergreen, which means it keeps its leaves year-round. Its native range covers Guangxi, Guangdong, and Hainan. It also includes western and southern Taiwan. It grows in warm temperate and subtropical areas within this range. Sources place it in dense woods and more open forest. It also grows on wooded slopes, often with fairly dry soils.

Sources give several height ranges for the places it grows. Plants For A Future places it in Hainan forests. These sites lie at 1,640–3,280 feet [500–1,000 metres]. Useful Tropical Plants gives 328–6,234 feet [100–1,900 metres]. It also cites records from 492–2,953 feet [150–900 metres]. These numbers show how high the sites lie above sea level. They do not show the vine's full height. The sources give no sound figures for mature height or spread. They say little about bark or leaf shape.

Plants For A Future says it flowers from July through September. Its seeds ripen from October through November. Male and female flowers grow on separate plants. A lone plant cannot use its own pollen to set seed. Grow both sexes to get fruit and seed. The red fruit has a round to oval shape. It forms an aggregate, or group of small fruit units. Each fruit has 30–50 of these units, called apocarps. Each unit holds one or two seeds. People gather fruit from wild plants for food.

Plants For A Future says it prefers moist soil when grown. It accepts sand, loam, and clay if the soil drains well. Soil may be mildly acid to neutral. The same source lists part shade and full sun. It places the vine at woodland edges and in dappled shade. Its evergreen leaves and climbing form suit woodland gardens. How much cold it can take is still unclear. The evidence thus gives no firm hardiness zone.

People can eat the fruit fresh or cooked. Plants For A Future rates its food value two out of five. Useful Tropical Plants notes local use as medicine but names no treatment. Plants For A Future reports no known uses as medicine. Neither source lists a known hazard. This does not mean the plant is safe for pets. The accounts name no specific pests or diseases. They give no detailed evidence of these risks in gardens.
