Symphyotrichum chilense (formerly Aster chilensis) is a species of flowering plant in the family Asteraceae known by the common names Pacific aster and common California aster.[3] It is native to the west coast of North America from British Columbia to Southern California and the Channel Islands. It grows in many habitats, especially along the coast and in the coastal mountain ranges. Despite its Latin name, it does not occur in Chile. Pacific aster blooms from June to October with violet rays surrounding a yellow center.
Description
Symphyotrichum chilense is a rhizomatous, perennial, herbaceous plant growing to heights between 40 and 120 centimeters (1+1⁄4 and 4 feet). The sparsely hairy leaves are narrowly oval-shaped, pointed, and sometimes finely serrated along the edges.[3] The inflorescence holds flower heads that open June–October[4] with centers of yellow disk florets surrounded by fringes of many narrow violet ray florets. The fruit is a seed, specifically a rounded, hairy cypsela with pappi.[3]
Distribution and habitat
Pacific aster is native to the west coast of North America in British Columbia, Washington, Oregon, and California[3] to Southern California and the Channel Islands.[4] Despite its Latin name, it does not occur in Chile.[3]
It can be found in coastal habitats including salt marshes, ocean dunes and banks, grasslands, and coniferous forests, at elevations of 0–500 meters (0–1,600 feet).[3]
