Sky Blue Aster

Sky Blue Aster (Symphyotrichum oolentangiense) adds a refreshing splash of soft blue and lilac flowers to the fall garden—just when most blooms are fading. This is a perfect choice for supporting late-season pollinators, providing much-needed nectar as bees and butterflies prepare for winter.

Unlike some asters that can spread aggressively, Sky Blue Aster is well-behaved and stays where it’s planted, making it suitable for more managed garden spaces. It thrives in dry, well-drained soils, even poor ones, and prefers low mulch levels—lightly brushing mulch away from the crown will help this short-lived perennial reseed and persist over time.

Why Choose Sky Blue Aster?

• Late-season color – Blooms in fall when few other plants do.
• Pollinator support – Vital nectar source for bees & butterflies.
• Garden-friendly growth – Non-aggressive and easy to manage.

Plant Sky Blue Aster in full sun to part shade and enjoy a low-maintenance burst of color that bridges the gap between summer and winter while feeding the last wave of pollinators.

• This is a relatively short-lived Aster - consider encouraging re-seeding by clearing the ground around this plant in the Fall and allowing some seedlings to take root in the following year.
