Silky lupine
Lupinus sericeus
Silky lupine thrives in well-drained soils with moderate moisture and at least 6 hours of sunlight, making it ideal for western native gardens and meadow plantings. Water regularly during establishment but avoid waterlogged conditions, as it is sensitive to root rot. It is a nitrogen-fixing plant that benefits surrounding soil health and requires minimal fertilization once established.
