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.
Description of the plant:
Blue Autumn is a special New York aster with large flowers. They are up to 4.5 m across, deep violet with rich yellow discs, have a lovely perfume, and are borne on about 30 cm tall stems. Blooming time is early September until mid October. Leaves are rich green, narrowly elongated, very resistant to common aster diseases. To multiply the number of flowers and to achieve a bushier plant pinching in late June is recommended. 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. Most of them are exceptionally hardy. This one has so far been observed to withstand -30°C (USDA zone 5) but is expected to take much deeper frost.
