Aster chilensis

Aster chilensis, or California aster, is a creeping perennial groundcover, usually about 1' x 3', but in early summer, when the blooms come, it grows to about 3' tall with gorgeous lavender and yellow blooms which attract tons of butterflies. They love the nectar. It continually blooms until mid fall..This plant is found all over the west coast down to S. America, hence the name chilensis.
