Family: Alliaceae

What it is like

Triteleia hyacinthina is a BULB growing to 0.7 m (2ft 4in) by 0.1 m (0ft 4in). See above for USDA hardiness. It is hardy to UK zone 4 and is not frost tender. It is in flower from May to August. The species is hermaphrodite (has both male and female organs) and is pollinated by Insects. Suitable for: light (sandy) and medium (loamy) soils and prefers well-drained soil. Suitable pH: mildly acid, neutral and basic (mildly alkaline) soils. It cannot grow in the shade. It prefers dry or moist soil.

Height (m): 0.7

How it is grown

Requires a rich well-drained sandy loam. Likes plenty of moisture whilst in growth followed by a warm dry period in late summer and autumn. Succeeds outdoors in a very sheltered warm position, otherwise it is best grown in a bulb frame. There are two basic forms of this species, a large white-flowered form grows wild in wet places whilst a smaller form is found on drier slopes. The hardiness zone has been given as 4, this is somewhat questionable, the plant is liable to be much less hardy.

Propagating it: Seed - best sown as soon as it is ripe in a cold frame. Alternatively, the seed can be sown in spring in a cold frame. Germination usually takes place within 1 - 3 months at 15°c. Sow the seed thinly so that there is no need to prick them out and grow the seedlings on in the pot for their first year. Give an occasional liquid feed to ensure that they do not become mineral deficient. Seedlings are prone to damping off so be careful not to overwater them and keep them well ventilated. When they become dormant, pot up the small bulbs placing about 3 in each pot. Grow them on in the greenhouse for another year or two until the bulbs are about 20mm in diameter and then plant them out into their permanent positions when they are dormant in the autumn. Division of flowering size bulbs in autumn. Dig up the clumps of bulbs, replanting the larger ones direct into their permanent positions. It is best to pot up the smaller ones and grow them on in a greenhouse for a year before planting them out when they are dormant in early autumn.
