Alpine aster (Aster alpinus)

Alpine aster

Features and Characteristics

Aster alpinus, commonly called alpine aster, is native to the mountains of Europe, including the Alps and Pyrenees. It typically grows in a slowly-spreading clump to 8-12″ tall. Daisy-like asters (to 1″ diameter) featuring blue-violet rays and yellow centers bloom in May-June. Flowers are usually solitary, appearing at the ends of slender stems. Untoothed, lanceolate-spatulate, dark green leaves (to 2” long) are mostly basal. Flowers are attractive to butterflies. Aster alpinus var. vierhapperi, commonly called Vierhapper’s aster, is native to the Altai Mountains in central Asia (primary range) plus Alaska and northwestern Canada, with several small disjunct populations in Idaho, Colorado and Wyoming.

Genus name comes from the Latin word aster meaning star for the shape of the flowers.

Specific epithet means alpine; from high mountains above the timber line.

Care and Maintenance

Grow in moderately fertile, medium moisture, well-drained soils in full sun. Tolerates light shade. Good air circulation helps reduce incidence of foliar diseases. This aster likes cool summer temperatures, and may struggle in the hot and humid St. Louis climate.
