The California Aster is a perennial of the west coast of North America, found from British Columbia, south to California. It is sometimes also called the Pacific Aster. It is a very versatile plant, enjoying all sorts of ecosystems including sandy and salty regions, grasslands as wells as various coastal coniferous forests.
The California Aster has 15-40 blue or purple, long and narrow ray florets with numerous tiny yellow florets in the centre disk.
It was once believed to be found in Chile but this was incorrect, however the error remains in its species scientific name, chilense.
