Estimated Native Range
Summary
Lupinus arboreus, commonly known as Yellow Bush Lupine, is an evergreen shrub native to coastal dunes and bluffs of central California. It can grow up to 2 meters (7 feet) tall in sheltered situations, but more typically reaches 1–1.5 meters (3–5 feet) in height. This species is adapted to a Mediterranean climate with mild, wet winters and dry summers, thriving in sandy, well-drained soils. Yellow Bush Lupine has a notable appearance with its silvery-green foliage and spikes of yellow or sometimes lilac to purple flowers, which bloom from late spring to early summer. The flowers are particularly showy, making it a favorite for ornamental use.
Yellow Bush Lupine is valued for its ability to stabilize sand dunes and its showy flowers, which attract pollinators such as bees and butterflies. It is often used in traditional and native plant gardens, as well as in wildlife gardens for its ecological benefits. While it requires minimal maintenance and is drought-tolerant, it is important to provide sharp drainage, especially when grown in non-native areas. It can be invasive outside its native range, so gardeners should consult local regulations before planting.CC BY-SA 4.0
