Top Garden Asters. Here are a few of the best fall-blooming asters. The USDA hardiness zone ratings are not absolute, but rather a guide, since many factors besides temperature affect hardiness. The exact bloom time will vary by region, and flower color may vary with soil type.
For example, the lowest average temperature in Zone 2 is -50 to -40 degrees Fahrenheit, while the minimum average temperature in zone 10 is +30 to +40 degrees Fahrenheit. See more. Suggested hardiness zones have been indicated for all trees and perennials available online from the Foundation. If a range of zones, for example, zones 4-9, is indicated, the tree or perennial is known to be hardy in zones 4, 5, 6, 7, 8, and 9. Suitable hardiness means a plant can be expected to grow in the zone's temperature extremes, as determined by the lowest average annual temperature.
