Common names: lao ya ban
Habitat : E. Asia – E. China, S. Japan, Korea, Manchuria Moist places in meadows in lowlands, near rivers and on wooded hillsides. Grassy slopes and hillsides from near sea level to 1700 metres in China.
Bulb growing to 0.15m at a slow rate.
It is hardy to zone 7 and is not frost tender. It is in flower from March to April, and the seeds ripen from May to June. The flowers are hermaphrodite (have both male and female organs).
The plant prefers light (sandy) and medium (loamy) soils and requires well-drained soil. The plant prefers acid, neutral and basic (alkaline) soils. It cannot grow in the shade. It requires moist soil.
Easily grown in a well-drained soil in a sunny position[1, 90]. This species is not fully hardy in Britain, the plants come into growth in the winter and need protection from severe weather and so are best grown in a bulb frame. Plants are dormant in summer but do not require protection from rain. Bulbs can be harvested in June after they have died down and then stored in a cool dry place, being planted out again in October.
Seed – best sown in a shady part of the cold frame as soon as it is ripe in early summer, or in the early autumn. A spring sowing of stored seed in the greenhouse also succeeds. Sow the seed thinly so that the seedlings can be grown on without disturbance for their first growing season – apply liquid feeds to the pot if necessary. Divide the bulbs once the plants have become dormant, putting 3 – 4 bulbs in each pot. Grow the on in the greenhouse for at least the next year, planting them out when dormant. Division of offsets in July. Larger bulbs can be planted out straight into their permanent positions, or can be stored in a cool place and then be planted out in late autumn. It is best to pot up smaller bulbs and grow them on in a cold frame for a year before planting them out when they are dormant in late summer to the middle of autumn.
Edible Parts: Leaves; Root.
Bulb – cooked. A source of starch. The bulb can be up to 4cm in diameter. Leaves – cooked. Unless you have more plants than you need this practise is not recommended since it will greatly weaken the plant.
