Nectaroscordum are deciduous bulbous perennials with linear, garlic-scented leaves and a tall leafless stem with a terminal umbel of bell-shaped flowers in early summer. N. siculum is a robust perennial with keeled basal leaves and a stem to 1.2m in height, with a terminal umbel of nodding, long-stalked, bell-shaped flowers combining cream, pink and green tints, followed by decorative, erect seed pods in late summer
Grows well in any moderately fertile, well-drained soil. May self-seed freely. Looks good in flower borders and beds. Also good in a wildflower meadow.
