Smooth Blue Aster

Smooth Blue Aster (Symphyotrichum laeve) brings season-long beauty and pollinator support to your garden with its glossy green foliage and abundant bluish-lavender blooms that appear in late summer and fall. This aster is ideal for pairing with other short- to medium-height natives and adds a reliable splash of color just as many plants begin to fade.

A host plant for the Pearl Crescent Butterfly, Smooth Blue Aster is both ecologically valuable and visually appealing. It’s a long-lived perennial that remains relatively compact and well-behaved, unlike more aggressive asters. While deer may browse it occasionally and it may develop harmless white spots some years, it remains a low-maintenance standout in any sunny planting.

Why Choose Smooth Blue Aster?

• Late-season blooms – Supports pollinators when few others are flowering.
• Non-aggressive & long-lived – Perfect for garden borders and mixed beds.
• Host plant value – Supports the Pearl Crescent and other beneficial insects.

Plant Smooth Blue Aster in full sun and well-drained soil to enjoy a durable, pollinator-friendly perennial that finishes the season strong.
