,

,

wild blue aster

Scientific Synonyms:

Description

Symphyotrichum oblongifolium is a beautiful Aster and one of the last wildflowers to bloom before winter. It has a mounding habit, and creates dense clumps up to 3 feet tall. Their color can vary greatly from delicate blue, to deep pink, or violet. The leaves are smooth, oblong and fragrant, hence the common name.

Cultivation

Aromatic aster will be happy most anywhere with good drainage and lots of sun. It is heat tolerant and especially likes south or west-facing slopes. Cut back when plants go dormant in late fall, or early winter. Bloom times are from September through November. Zones 4-8

Propagation

Propagate from seed, outside in fall, or by softwood cuttings in late spring. It spreads naturally by stolons.

Additional Notes

The species got the common name aromatic aster, because the leaves exude a fragrance when crushed. The flowers however, are only mildly. Symphyotrichum is a genus of about 90 species that were formerly classified under the Aster genus. The majority of these species are native to North America.
