Aster alpinus, commonly known as alpine aster, is a low-growing perennial plant valued for its compact growth and daisy-like blooms. It develops clumps of narrow foliage and produces single flowers in shades of purple, blue, pink, or white during the late spring to early summer period. This plant is well adapted to cool and temperate climates and performs best in full sun with well-drained soil. It is commonly used in rock gardens, borders, and alpine planting, where it establishes gradually from seeds under suitable conditions.
