Asters (Michaelmas daisies) are a genus of perennials which flower through September and October. The provide lovely Autumn colour when many other plants are giving up for the year. They have daisy-like flowers in blues, pinks and white in a variety of sizes.
They are easy to grow but older varieties can be prone to powdery mildew in very dry summers. Although they can be grown in most soils they prefer soil that is moist, but well-drained, and has plenty of humus in a spot that is either in full or part sun. They are easy to propagate by dividing large clumps.
