Symphyotrichum pilosum (Aster pilosus)

Share on

Common Name:  Hairy Aster, Pringle’s Aster, Frost Aster, Hairy Oldfield Aster, Downy Aster, White Old-field Aster

Full to part sun; moderately wet to dry moisture level; tolerant of a range of soils including loamy, sandy and clay; pH ?.   2 to 5 feet height (typically 3 – 3 ½ feet); white flowers; blooms in fall for about 1 ½ months; spreads aggressively by both rhizomes and self-seeding.

Germination Code: C(60), D

Native Region: Statewide

Large plant with a shrubby appearance and covered with plentiful, small, daisy-like flowers ½” – ¾” across.  Easily grown.  Common in disturbed areas, open woodlands, weedy meadows, along railroads, and in gardens.  This plant is a survivor and able to compete well with common Eurasian weeds.  In a naturalized setting, it is likely to appear on its own and not need to be purchased for planting.  Attracts butterflies, moths and many varieties of bees. Seeds provide food for some bird species. Although it is often described as weedy, it provides a major benefit to pollinators and can help fill the gap left by the loss of so many other plant species that benefit pollinators.
