This species of aster needs to be planted in an open and reasonably sunny position to achieve peak flowering. Needs good air circulation to limit mildew issues and prevent the bottom leaves from dropping. Pinch back 1/3 of the foliage twice before early summer, to maintain shape and foliage vigour.
