Habit: Upright, tufted.
Type: Cormous perennial.
Origin: West coasts of North and South America.
Hardiness: Hardy in coastal and mild regions of the UK.
Grow in a sheltered spot in full sun, ideally at the base of a south facing wall. They will grow in most types of free draining soil, except heavy clay.
Plant bulbs in early autumn at a depth of 2.5-3in (6-8cm), spacing 3in (8cm) apart. Prepare the soil first by forking it over and incorporating a handful of general-purpose fertiliser. Best grown in large groups rather than individually.
Useful for planting between shrubs. Shorter varieties are suitable for patio pots and containers.
Excellent as cut flowers.
Protect from frost and excessive winter wet. Once established they should flower for several years in mild areas of the UK.
Generally pest and disease free
Remove and replant offsets every four years or so.
