New York aster is an old time favourite in Czech and Slovak gardens. These plants are carefree and flower over a long period. Since they are so attractive and popular breeders keep coming up with new, improved varieties that brighten up our early autumn gardens.

Professor Anton Kippenberg is a handsome, dwarf variety of New York aster. It produces semi-double light blue-violet flowers from late August until late October. Compared to other modern varieties with bright and cheerful colours this one looks very calm and as peaceful as a zen garden. To keep it compact and to achieve a neat cushion shape pinching in late June is recommended. The plant will make more flowers and will look more symmetrical.

These asters are more resistant to common aster diseases such as powdery mildew and black spot if grown in constantly moist, rich soil (any pH). Grow them in full sun and fertilize annually for profuse flowering. Cut back to ground level in early spring. Hardy to about -40°C (USDA zone 3).
