About Tree lupine
Lupinus arboreus, commonly known as tree lupine, is a perennial shrub belonging to the Fabaceae family, native to the Californian coast. It is characterized by its dense clusters of fragrant flowers, ranging from bright yellow to purple, and its silvery-green foliage. It is ideal for coastal gardens, slopes, and as an ornamental plant in borders or beds, adding a wild and colorful touch.
Native range
Pacific Coast of California and Oregon, USA
Care tips
It requires full sun for optimal flowering and prefers well-drained, sandy, or slightly acidic soils. It is drought-tolerant once established, so watering should be moderate, allowing the soil to dry out between waterings. Avoid over-fertilization, as being a legume, it fixes its own nitrogen, and an excess could promote foliage growth at the expense of flowers.
