Herders sometimes favor hybridization because genes from wild progenitors are thought to enhance the hardiness of domestic stock.

These numbers reflect the plant’s ability to survive the average minimum winter temperatures in the hardiness zones listed.

In late 2023, the Department of Agriculture seemed to validate their experiences when it released its updated plant hardiness zone map — moving more than half of the U.S. into warmer climate zones.
