Suggested
hardiness zones have been indicated for all trees and plants
available at our nursery. If a range of zones, for example,
zones 4-9, is indicated, the tree 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.
Keep
in mind that local variations such as moisture, soil, winds,
and other conditions might affect the viability of individual
plants.
