Zones for the Pandorea Bower Vine

Zone 9a and 8

• Pandorea bower vines planted in these USDA hardiness zones may die back to the ground during periods of freezing weather. If the roots are protected by a thick layer of mulch, however, the plant will bloom again in the spring. Average low temperatures in USDA zone 8 are between 10 and 15 degrees Fahrenheit. The minimum temperatures in USDA zone 9a average between 20 and 25 degrees Fahrenheit.

Zone 9b

• USDA zone 9b is the coldest zone where this vine will remain evergreen year-round if given proper care. The minimum temperatures in zone 9b drop to between 25 and 30 degrees Fahrenheit, which means the ground will occasionally freeze, but not so much so that the plant will necessarily die back to the ground. Still, a 3-inch layer of mulch will help protect the roots of the vine.

Zone 10

• Minimum temperatures in USDA zone 10 range from 30 to 40 degrees Fahrenheit. Freezing temperatures are rare.

Zone 11

• Pandorea jasminoides vines thrive in this zone, which, along with zone 10, covers most of Florida. Temperatures almost never drop below 40 degrees Fahrenheit.

States

• Areas of the United States classified as USDA growing zones 8 through 11 include parts of Washington, Oregon, California, Nevada, Utah, Texas, Arizona, New Mexico, Alabama, Georgia, Florida, Mississippi, Oklahoma, Arkansas, Virginia, Maryland, Delaware, Tennessee and North and South Carolina.
