Bloom Time: July through October
Aster amellus is a perennial herbaceous plant that grows up to 20 inches (50 cm) tall. The stem is erect and branched, and the leaves are dark green. Basal leaves are obovate and petiolated. The cauline ones are alternate and sessile, increasingly narrower, and lanceolate. Flowers are lilac and appear from July through October. Seeds are an achene that ripens in October.
How to Grow and Care
Divide mature plants in spring, just as the new shoots begin to grow. This should be done every few years to avoid crowding of plants.
As with many other flowering plants, deadhead (cut back spent flowers) to make room for newer blossoms, this will extend the health and flowering of your plants. Be sure to deadhead early on in the blooming season. Blooming will be reduced if done too late. This will also restrain unwanted reseeding, which will cause plant overcrowding.
Remember, Asters are prone to mildew, so be careful to plant them in areas with good circulation and good sun exposure.
As with other flowering plants, do not allow water to saturate leaves. Be sure to water at the plant's roots to prevent mildew and mold. Drip irrigation and utilization of a soaker hose work very well in watering these plants. See more at How to Grow and Care for Aster.
