U.D. Department of Agriculture hardiness zones for the Boston fern are 9, 10 and 11, all of which have average low temperatures of 20 to 40 degrees Fahrenheit. Ideally, the temperature for outdoor ferns is between 65 and 95 degrees Fahrenheit, but the Boston fern will tolerate much colder temperatures.
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.
