Take a walk through an English garden and discover flowers that are common not only in England, but in North America as well. The hardiness zones in England correspond to the same zones in the United States. England has four zones from 7 to 10A, with most of the country in zone 8. This is equivalent to the southern United States as far south as parts of northern Florida.
