Actually more like a shrub than a tree, the Tree Lupin is a relative of the Texas Bluebonnet and one of the largest of the lupins. It is native to California. The leaflets are finger-shaped, growing in a circle at the tip of the stalks and somewhat hairy. Flowers in spring or summer with upright clusters of sulfur-yellow flowers.
Varieties are available that have white or purple flowers.
Needs good drainage, but not particular otherwise as to soil type. Drought tolerant once established. Good choice for coastal gardens. Height to 8 feet.
