California Aster

California Aster brings a profusion of lavender-blue, daisy-like flowers just when late-season gardens need fresh color. From late summer into fall, its bushy mounds of narrow green foliage become covered in starry blooms, creating a soft, meadow-like display that pairs beautifully with grasses, goldenrods, sages, and other dry-garden natives.

Adaptable and easy to grow, California Aster is especially useful in coastal settings where it can tolerate sandy soils, salt spray, and breezy conditions. Its nectar-rich flowers support bees, butterflies, and other pollinators late in the season, helping extend habitat value well beyond the spring bloom window. It can spread into a colony where conditions suit it, making it a strong choice for seaside gardens, naturalized areas, slopes, and informal borders.

Why Choose California Aster?

• Lavender-blue flowers bloom from late summer into fall
• Provides valuable late-season nectar for pollinators
• Tolerates coastal conditions, including sandy soils and salt spray
• Bushy habit adds fullness and texture to naturalistic plantings
• Excellent for meadows, slopes, seaside gardens, and habitat borders
  

Plant California Aster in full sun to light shade with well-drained soil, and give it room to spread naturally. Cut back old stems in late winter or early spring, and thin or divide colonies as needed to keep growth balanced.

• Prune lightly in early spring to shape and promote denser growth.
• Divide every few years in early spring to maintain health and manage spread.
• Allow seedlings to naturalize in informal garden areas or remove to maintain neatness in more structured settings.
