Summary

White Brodiaea is a bulb-forming perennial from western North America that grows from a corm and forms clumps. It features slender stems 30–60 cm tall bearing an umbel of 10–40 white flowers (often with a lavender tint and green mid-veins) and long, narrow basal leaves 10–40 cm long; plants occur in grassy flats and vernal wet meadows up to 2,000 m and are drought-tolerant once established.

It prefers full sun and well-drained soils, with moisture during growth and a warm, dry period in late summer to autumn. Propagation is by seed or division, with seed germination 1–3 months at 15°C and division of flowering-size bulbs in autumn; hardy to USDA zones 4–8; easily grown with low maintenance and a tendency to naturalize, forming drifts in rock gardens and meadows or cottage gardens and suitable for container culture.
