Also known as Fall Asters, these are terrific favourites for autumn colour in the perennial border. Plants form bushy clumps, bearing loads of small daisy flowers. This is a compact selection with fluffy, double soft lavender-blue blossoms. Pinch plants before July to keep them especially low in habit. Excellent in containers. Most asters will be troubled much less with powdery mildew when grown in a moist, rich soil.
