Triteleia

Asparagaceae

Triplet Lily

They were once classified as lilies but are no longer. Like lilies, their flower parts are in groups of three, hence their common name. These cormous plants have narrow linear to lanceolate mid-green leaves to 40cm long. Flowers are produced in the summer and are typically borne in clusters resembling umbels. The flowers are tubular to begin with becoming funnel-shaped or star-shaped.

Uses

Woodland garden, natural garden, meadow garden, alpine garden, rockeries, border plants, massed planting.  

Culture

These plants will grow in most moist but well-drained soils, though they prefer enriched sandy soils. They need a sunny position with shelter from winds. They require water during the growing season, followed by dry soils during dormancy. 

Propagation

They are best grown from seeds planted as soon as they are ripe in summer. Seeds may also be stored and planted the following spring. Grow them in the greenhouse for several years before planting out. Alternatively, lift and divide bulbs in the autumn when dormant. If divided bulbs are small pot them up and grow on in the greenhouse for a year or two before planting out permanently.
