What is a zone 7 climate?
Hot summers and mild but pronounced winters give Zone 7 sharply defined seasons without severe winter cold or enervating humidity. The climate pleases plants that require a marked seasonal pattern to do well—flower bulbs, peonies, lilacs, and flowering cherries, for example. All plants have their comfort zone—a specific climate where they grow optimally. Each plant likes to grow in its preferred climate and weather conditions. Planting plants in climates that are too hot or too cold will stress them and could strain their growth.
