Symphyotrichum oolentangiense 100 Seeds – Sky Blue Aster Heirloom Non-GMO Native Pollinator Flower

Symphyotrichum oolentangiense, commonly known as Sky Blue Aster, is a native perennial wildflower prized for its late-season display of soft blue-violet blooms. This heirloom, non-GMO variety brings a natural, meadow-like feel to pollinator gardens, native plantings, and perennial borders. Its daisy-like flowers appear in loose, airy clusters that sway gently in the breeze, attracting bees, butterflies, and other beneficial insects when many other plants have finished blooming.

Sky Blue Aster is a versatile choice for cottage gardens, wildflower meadows, rain gardens, and naturalized areas. It pairs beautifully with goldenrod, coneflowers, and ornamental grasses, extending seasonal interest well into autumn. As a North American native, it supports local ecosystems while adding reliable color and texture to the landscape.

Planting & Care

Sky Blue Aster seeds can be sown directly in the garden or started indoors. For best results, cold-stratify seeds by refrigerating them for 4 to 6 weeks before sowing. Surface-sow seeds and press them lightly into the soil, as they need light to germinate. Keep the soil consistently moist but not waterlogged. Germination typically occurs in 2 to 4 weeks at around 65 to 70°F.

Once seedlings have several sets of true leaves, thin or transplant them to their final spacing. Water regularly during the first growing season to help plants establish. After establishment, Sky Blue Aster is relatively low-maintenance and benefits from a light mulch in colder zones. Deadheading spent blooms can encourage additional flowering, while leaving some seed heads provides food for birds in winter.
