The name under which this plant circulates in horticultural collections likely covers an uncertain botanical identity, distinct from the wild Himalayan species to which it refers. The true Aster himalaicus is a high-altitude plant, strictly rupicolous, with a compact habit and summer flowering; the plant cultivated under this name presents significantly different characteristics that suggest a hybrid or an old garden selection whose exact origin has been lost.
In cultivation, it forms loose and natural clumps 20 to 30 cm in height, with upright but flexible stems, colored reddish, bearing oval to elliptical leaves, a bright green, slightly velvety to the touch. The flower heads are generous, with pale lavender to lilac rays, fine and numerous, centered with a bright yellow disc well contrasted.
Its spring flowering, from April to May, is uncommon in this genus, and constitutes one of its most unique assets in collection. It requires well-drained soil, a sunny to semi-shaded exposure, and proves hardy and undemanding once established.
