Tricyrtis latifolia

Tricyrtis latifolia, or broadleaf toadlily, is a perennial in the lily family. It grows to about 2 feet (0.6 metres) tall. Kew lists Japan as its native range. Plants For A Future also reports it from central China. That source places it in mountain woods across Japan. In China, it records the plant in forests and along their edges. These records include Hebei, Henan, Hubei, Shaanxi and Sichuan. The plant suits temperate climates and woodland garden sites.

Flowers appear from June to July, according to Plants For A Future. Each flower has both male and female organs. Insects pollinate the flowers. A sunny site can bring flowering forward when soil stays moist. The supplied species accounts give no flower colour or fruit details. They also lack a clear account of leaves and stems. The RHS lists Tricyrtis bakeri and Tricyrtis puberula as synonyms. Its page marks the name's status as unresolved.

Grow this plant in rich soil with plenty of humus. It needs good drainage, but the soil should hold moisture. A light sandy loam suits it, as do loamy soils. Choose mildly acid to neutral soil. Light shade beneath trees is a good match for its needs. It also suits shaded borders and the edges of woodland gardens. Full sun works where soil stays moist through the growing season. Plants For A Future advises more sun in northern Britain.

Chicago Botanic Garden lists USDA hardiness zones 6–8. Plants For A Future reports cold tolerance near −4°F (−20°C). It advises an organic mulch during long cold spells without snow. Slugs can cause serious damage, so watch for attacks. Plants For A Future does not flag it as weedy. Divide plants in spring, just before new growth starts. Large divisions can go straight into their final sites. Grow smaller pieces under cover until they establish well. Sow fresh seed in a cold frame when ripe. Stored seed needs twelve weeks of cold treatment at 41°F (5°C).

Plants For A Future lists cooked leaves and young shoots as edible. It gives their food value a low score. The source reports no known hazards, but provides no pet-safety evidence. It lists no known medicinal uses or other practical uses. Its main garden role here is a flowering perennial for moist woodland sites.
