Disporum smilacinum aka Star Flower Fairybell

Disporum smilacinum is a small perennial called Japanese fairy bells. It belongs to the Colchicaceae family. Its native range spans parts of temperate eastern Asia. These include southern Sakhalin, the southern Kurile Islands, Korea, and Japan. It also grows in northeastern Shandong in China. It is not native to Britain or Ireland. In Japan, it grows in woods on hills and foothills. Chinese records place it in forests from near sea level upward. Some sites reach about 5,250 feet [1,600 metres].

The plant reaches about 1.6 feet [0.5 metres] in height. It grows from rhizomes, which are underground stems. This makes it a perennial with growth below ground. The supplied species records give no firm mature spread. They also give little detail about its leaves or stems. Its small size suits the scale of a woodland planting. Plants For A Future lists it for shaded woodland gardens and edges.

Flowers appear from April to May. Each flower has both male and female organs. Seeds ripen from September to October. The supplied species evidence does not describe flower colour or fruit form. These gaps limit a fuller account of its seasonal looks. The bloom and seed dates still mark its spring and autumn cycle.

Choose a partly shaded site with moist soil. The species listing accepts sandy, loamy, and clay soils. It also accepts mildly acid, neutral, and mildly alkaline conditions. Plants For A Future gives no confirmed British hardiness rating. It suggests outdoor survival across much of Britain from the native range. That is an estimate, not a tested hardiness limit. Its more detailed growing notes draw on the genus as a whole.

Plants For A Future recommends sowing fresh seed in a cold frame. Keep the seed compost moist and free of lime. Stored seed needs six weeks of cold treatment before sowing. Germination may take three to six months or longer. Keep young plants under glass through their first winter. Plant them out after the last expected frost. Spring division offers another way to raise plants. The source records cooked young leaves and an underground part as edible. It gives no known medicinal uses or hazards. That does not establish safety for people or pets. It flags no weed potential.
