This list will be used to identify false or misleading USDA cold hardiness zone labeling of plants offered for sale which is a violation of Minnesota Statute 18H.14. This statute requires that:
(a) Plants, plant materials, or nursery stock must not be labeled or advertised with false or misleading information including, but not limited to, scientific name, variety, place of origin, hardiness zone as defined by the United States Department of Agriculture, and growth habit.
(b) All nonhardy nursery stock as designated by the commissioner must be labeled correctly for hardiness or be labeled "nonhardy" in Minnesota
If cold hardiness labeling is present, it must be consistent with this list. If the correct cold hardiness is on the label nothing further is needed. However, plants that are not labeled for cold hardiness and are not cold hardy in the area in which they are being sold must be labeled "nonhardy".
Cultivars are listed separately if supporting information has been presented. Particularly if the cultivar varies in hardiness from the species. If the cultivar is not listed refer to the species for appropriate cold hardiness zone.
An annual review has been completed in September 2017. This revision is expected to remain unchanged through September 2018.
