In the garden

Lupinus albifrons originates from California and Oregon and is adapted to open, dry sites in its native range. As a shrub with distinctly silver, pinnate leaves it carries clusters of pale blue to violet flowers in summer (June to August). The combination of cool-toned flowers and pale foliage is a defining feature. Grow it in a sunny position with sharply drained soil; full sun and well-drained conditions suit it best, and it tolerates dry to medium soil moisture. Avoid heavy, waterlogged ground. Establish plants in a free-draining mix and give a sunny, sheltered aspect where possible; that orientation supports flowering in UK summers. In UK gardens Lupinus albifrons works well in gravel or dry borders, sunny slopes and coastal locations where drainage and exposure match its preferences. Because all parts are toxic, situate it away from play areas and where pets roam. Prune only to shape and remove dead wood, taking care with cut stems, and consider gloves when handling to reduce contact with sap.
