In the garden
Quamash (Camassia leichtlinii 'Orion') is a perennial from western North America that offers a distinct spring presence with a flowering period in May to June. It belongs to the genus Camassia and is grown for its concentrated spring display rather than summer interest. Choose a sunny, open position: the cultivar requires full sun and performs in a range of soils from sandy through loam to heavier clay, provided the soil remains moist but well-drained. It carries an H7 rating, which means it is fully hardy in UK gardens; the USDA equivalent is zones 3–7. Avoid deep shade and very dry sites where moisture cannot be maintained in spring. In the garden it works well in sunlit herbaceous borders, naturalised drifts where soil conditions suit, and moist edge plantings that receive good light. Plant where it can be seen in spring, as the main interest occurs during the May to June flowering window and then quiets afterwards, allowing later perennials to take over.
