Aster himalaicus - ​Many-rayed lavender-blue daisies, 1.5 to 2 inches in diameter, with yellow discs at the heart of each virtually cover the mound of medium green foliage in early summer. A robust herbaceous perennial, Himalaya Aster has been happy at home in full sun in our xeric garden planted in average soil. When in flower this plant is pure joy. Established pot grown perennial from cutting grown or division.
