Lindera umbellata

Lindera umbellata belongs to the laurel family, Lauraceae. This shrub is deciduous: it sheds its leaves for winter. It comes from northern and central Japan. Plants For A Future lists Hokkaido and Honshu within that range. Kew lists its growth form as a shrub or tree. The garden account calls it a shrub reaching 10 feet [3 metres]. It suits the edge of a woodland garden. Its home has a temperate climate, which fits gardens with cold winters.

Flowers appear from April to May. Each plant bears male or female flowers, never both. A lone plant cannot use its own pollen to set seed. Grow both sexes if you aim to get seed. The supplied species account does not state the flower colour. It gives no fruit details or specific leaf or bark traits. These gaps limit what we can say about its looks.

Choose part shade or light that filters through trees. The shrub can also grow in full sun. It needs moist soil that holds water and does not dry out. It prefers rich soil with added leaf mould. It can grow in sand, loam or clay soils. Give it lime-free, acidic soil; quite acidic ground also suits it. Plants For A Future lists USDA zones 6–9. It also reports cold tolerance near 5°F [−15°C]. A sheltered woodland edge fits the needs the source lists.

You can prune to the base to renew the shrub. Spread hard cuts over several seasons, not all at once. To grow new plants, sow ripe seed in autumn. Sow it under cover in a greenhouse. Seed soon loses its power to sprout, so keep it from drying. Move seedlings to their own pots when large enough to handle. Keep them in the greenhouse through their first winter. Plant them out in early summer. Other listed ways to grow new plants include layering. The source also lists July cuttings from half-ripe wood.

The source notes limited food use and no known use as medicine. It describes a decoction, a boiled extract, poured over rice or millet. It does not name the plant part used to make it. It lists edible oil but does not say how to make it. Seed oil has a separate recorded use as lamp fuel. Plants For A Future reports no known hazards or weed potential. This does not prove the plant is safe for people or pets. The supplied species evidence names no specific pests or diseases.
