In the garden

Camassia leichtlinii 'Atroviolacea' is a perennial from western North America that brings its main display in May to June. It is suited to locations where it receives uninterrupted sun through the spring months and can tolerate the cooler winters indicated by its USDA hardiness range (zones 3–7) and UK hardiness rating of H7 (fully hardy). Select a site in full sun with soil that holds some moisture yet drains freely; this cultivar accepts sandy, loamy or clay soils provided they are moist but well-drained. Avoid waterlogged hollows and ensure soil structure allows excess water to move away, especially over winter. Established plants endure typical UK winters without additional protection, as indicated by the H7 rating. In the garden it works well in sunny mixed perennial borders or planted in groups for a naturalised effect where spring moisture is present. Because its flowering is concentrated in late spring, it complements earlier spring bulbs and perennials that follow into summer. Expect reliable flowering in May to June in suitable, exposed sunny sites across the UK.
