Growing Information

Rainbow Mix Aster thrives in full sun and fertile, well-drained soil. Plants typically grow 18 to 30 inches tall depending upon growing conditions and develop sturdy stems capable of supporting numerous large blooms. Their upright habit makes them ideal for both garden display and cut flower production.

Flowering begins in midsummer and continues until frost. Regular harvesting or deadheading encourages continuous bloom production and keeps plants attractive throughout the season.
