Description Northwest gardeners can look forward to the month of September when New York Aster blooms start to appear. The various shades of purple flower heads will help brighten up the landscape. They are called Michaelmas daisies because they bloom around St. Michael's Day (September 29).

  Morphology:
This herbaceous perennial grows to 2’ in height with an equal spread. It bears dark green lanceolate leaves.

Flowering begins in early September and continues through first frost. Flower heads (1” in diameter) range from white to violet-purple with yellow centers. The plants may be cut to the ground after blooming. They provide color for us and a late-season source of pollen for bees and other pollinators.

  Adaptation:
This is a sun loving perennial that grows well on most well-drained garden sites.

  Pests:
The main plant disease is powdery mildew which consists of a whitish growth that may appear on leaves from late June or July. Powdery mildew is most prevalent on sites with poor air circulation.
