(='Yopuff') Also known as Fall Asters, these are terrific favorites for autumn colour in the perennial border. Plants form bushy clumps, bearing loads of small daisy flowers. This is a medium-sized selection with clean white petals surrounding a yellow eye. Pinch plants before July to maintain a cushion effect. Excellent for cutting. Most asters will be troubled much less with powdery mildew when grown in a moist, rich soil. USPP#15691: unlicensed propagation prohibited.
