This California native is a low growing, late summer bloomer that shines when much of the garden is quiet. It works well in the front of a low water perennial bed or native plant border.

Calfornia aster looks better if regularly deadheaded. After it is done blooming in the fall, we recommend shearing it back to to the ground to keep a tidy look in the garden. The plant will cheerfully return when winter is over.

California aster was a new plant in the Palo Alto Demonstration Garden and we found that it spread very rapidly even without supplemental water. We have removed it from the native plant bed. It might work better in a situation where a rapidly spreading plant is needed for erosion control rather than in a small, mixed perennial bed.
