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.
The 1990 map shows 10 different zones, each of which represents an area of winter hardiness for the plants of agriculture and the natural landscape. The USDA introduced zone 11, representing areas that have average annual minimum temperatures at or above 4.4 Â°C (40 Â°F) and that are therefore essentially frost-free.he criterion is the average number of days per year when the temperature exceeds 30 Â°C (86 Â°F). The AHS Heat Zone Map for the US is available on the American Horticultural Society website.
