100 Frost Aster Seeds | Symphyotrichum pilosum | White Native Wildflower for Pollinator Gardens

Frost Aster, also known as Symphyotrichum pilosum (formerly Aster pilosus), is a hardy native wildflower that brings late-season beauty to gardens and natural landscapes. This perennial produces clouds of small white flowers with subtle yellow centers, creating a frosty appearance that gives the plant its common name. Blooming from late summer into fall, Frost Aster is a valuable nectar source for pollinators when many other flowers have finished for the season.

Its daisy-like blooms and bushy, upright habit make it an excellent choice for pollinator gardens, meadow plantings, and native wildflower borders. Frost Aster is adaptable and low-maintenance, thriving in a range of conditions and returning year after year in suitable climates.

Planting & Care

Sow Frost Aster seeds indoors 6-8 weeks before the last frost, or direct sow in fall or early spring. Press seeds lightly into the soil surface; they need light to germinate. Keep the soil consistently moist until germination, which typically occurs in 14-30 days at 65-70°F. Once seedlings have several sets of true leaves, transplant them outdoors after the danger of frost has passed.

Choose a sunny to partially shaded location with well-drained soil. Water regularly during the first growing season to help plants establish. Once established, Frost Aster is drought-tolerant and requires minimal care. Deadhead spent flowers to encourage additional blooms, or leave seed heads for birds. Divide clumps every 2-3 years in early spring to maintain vigor.
