Grapeleaf anemone (also sold as Japanese anemone) is the perennial that saves the late-season cutting garden — tall, wiry stems carrying simple, elegant blooms of 5 petals in white or soft pink with a yellow central boss, blooming from August through October when almost everything else has finished. The grape-shaped leaves and architectural stem structure add a quiet elegance.
Spread by underground runners; once established, it can colonise vigorously — position accordingly. Cut when the flowers are fully open; the buds visible on the stem will continue to open in succession. Outstanding paired with late dahlias, autumn hydrangea, and the last zinnias of the season.
Powdery mildew
White or grey powdery coating on leaves — usually starting on older growth in humid conditions or when nights cool.
Improve air circulation by thinning plants. Apply neem oil or potassium bicarbonate spray at first sign. Avoid overhead watering.
