Zone 7 has warmer temperatures than Zone 6 with an average winter temperature of 10 to 20 degrees Fahrenheit. This warmer climate allows for a greater variety of plants including fruit trees like apple and peach trees as well as shrubs such as rose bushes and rhododendrons. Perennials like clematis vines and lily-of-the-valley also do well in this zone because they are more tolerant of the heat than some other varieties of plants.
Zone 8 is the warmest climate zone in Pennsylvania with an average winter temperature of 20 to 30 degrees Fahrenheit. This warm climate makes it ideal for growing tropical plants like palms or citrus trees as well as perennials such as daylilies or Shasta daisies that require more heat than other varieties of flowers or shrubs might need. Trees like magnolias or crepe myrtles can also thrive in this warm environment due to their ability to tolerate heat better than some other types of trees might have difficulty withstanding the warmth here.
Finally there is Zone 9 which has an average winter temperature of 30 degrees Fahrenheit or higher! This warmest climatic region makes it possible for gardeners to grow even more unusual types of plants including cacti or succulents which require less water than many other varieties do but still provide interesting foliage or blooms throughout the year depending on the type chosen!
