Willow Aster Seeds – 100 Heirloom Non-GMO Symphyotrichum praealtum Purple Pollinator Flower

Willow Aster (Symphyotrichum praealtum) is a native perennial prized for its late-season display of soft purple blooms. This heirloom, non-GMO variety brings delicate color to meadows, pollinator gardens, and naturalized landscapes. Its willow-like foliage and upright habit make it a graceful addition to borders and wildflower plantings.

In late summer and fall, the abundant flowers attract bees, butterflies, and other beneficial insects, providing an important nectar source when many other plants have finished blooming. Willow Aster is a resilient native that returns year after year in suitable climates.

Planting & Care

Sow Willow Aster seeds indoors 6–8 weeks before the last frost or directly outdoors in late fall for natural stratification. Press seeds lightly into the soil surface; do not bury deeply, as light aids germination. Keep the medium evenly moist at around 65–70°F. Germination typically occurs in 14–30 days.

Once seedlings have several sets of true leaves, harden them off and transplant to a sunny location with well-drained soil. Water regularly during the first growing season to help roots establish. Mature plants are relatively low-maintenance; divide clumps every few years to maintain vigor. Deadhead spent blooms to encourage continued flowering, or leave seed heads for birds.
