White wood aster

Eurybia divaricata

Preview: plant data is awaiting horticulturist review. A professional horticulturist hasn't reviewed our plant table yet. Lists still follow fixed rules for zone, sun, pets, deer and invasive status.

White wood aster is a perennial hardy in zones 3–8. Expect 1–2 ft of height and 1.5–2 ft of spread; our lists space it 1.5 ft apart. It does best in part sun to shade with little water once established. Expect white flowers in August to October. In a FloraVista list it usually plays the filler role: a flowering plant that fills the middle or front of the bed. It is native to the Northeast, the Mid-Atlantic, the Southeast and the Midwest. Deer may browse it when other food is short, and it is not listed as toxic to dogs or cats. Our rules leave it out of lists in Florida and the Gulf and the Desert Southwest, where summer heat, humidity or mild winters hold it back even inside its zone range.
