In the garden

Allium 'Millenium' is a bulbous perennial in the Amaryllidaceae and part of the genus Allium. It produces a basal set of linear, channeled or flat leaves and flowers during the period from May to July. The plant's habit suits sites where a predictable mid-season display is required. Site choice is important: give Allium 'Millenium' full sun on a loam soil with neutral pH and good drainage. A south-facing, sheltered aspect reduces wind exposure and helps flowering stems remain upright; H4 translates as average winter hardiness for the UK, so avoid the coldest, most exposed locations or give additional shelter in marginal areas. Well-drained soil is essential to prevent prolonged waterlogging around the bulbs. Use this Allium in mixed borders, gravel or rock gardens and containers where drainage can be controlled. In containers select a loam-based compost that drains freely and locate pots in direct sun but away from prevailing winds. Flowering runs from May to July, so position Allium 'Millenium' where that seasonal window complements surrounding plants and garden use.
