Propagation
Lift and divide the bulbs when the foliage dies off and replant during autumn. When planting out space the bulbs 100 mm (4 in) apart and 50 mm (2 in) deep. The bulbs should be scooped.

Sow fresh seeds in a well-drained media and place in a cold frame to germinate in 2-4 weeks. Stored seeds require 2-3 months cold stratification and there should be sow thinly in a container and it left undisturbed for the first season. Flowers are produced within 4-5 years from seed.

Botanic information
Leaf: The glossy dark green soft leathery textured basal linear leaves are up to 400 mm (16 in) long by 12 mm (˝ in) wide with an acute apex. The pale green underside is slightly keeled and the leaves become lax with age and then die off during a summer.

Flower: The nodding campanulate (bell-shaped) flowers are white with a single green dot on each of the 6-tepals and have a slight chocolate scent. The flowers are solitary or are arranged in an umbel of 2 to 8 on a long slender pedicle and are held above the foliage on a leafless scape that is up to 300 mm (1 ft) tall. They appear during late spring and pollinated by bees.

Fruit: The small black berry contains several tiny viable seeds but the plant is commonly reproduced vegetatively.
