A list of the Best Fall-blooming Perennials
1. Aster
Asters are a genus of plants with star-shaped flowers that fill your garden throughout fall. This genus has about 600 plants that are a part of the genus you can choose to grow. Asters are native to Eurasia and North America.

Asters produce masses of flowers with a wide range of colors, from softer blues and purples to bright, luminescent red. These blooms attract many pollinators due to the end of most bloomers, commonly bees that love the nectar.

Asters are easy to grow if you provide them with the right growing conditions. Grow them in full sun or part sun in rich, loamy, well-drained soil.
Keep the new plant moist and continue frequently watering until the end of the blooms. Furthermore, note that the Asters will do well if you grow them in hardiness zones three through eight to reach a mature height of about eight feet tall.
Water these plants at the base, not splashing the water over the foliage. Moisture on the foliage encourages powdery mildew and other fungal diseases to form that destroy this plant.
Use insecticidal soap to clean the leaves if you notice any of these diseases forming. Add organic mulch to retain moisture and help the nutrients break down quickly. Deadhead for more blooms.
