Zone 6 (-10° to 0°): This zone bands throughout the middle of the country going through the eastern border of Colorado and New Mexico, through Kansas, Missouri, Illinois, Kentucky, Ohio, West Virginia, Southern Pennsylvania, Maryland, Delaware, New Jersey and Connecticut. Zone 6 is the largest zone and includes most of the states. Tomatoes, Common boxwoods, and Coneflowers are excellent plants for this area.
Zone 7 (0° to 10°): This is the zone where the plants become slightly less hardy due to the warmer temperatures. Arizona, New Mexico, Northern Texas, Oklahoma, Arkansas, Tennessee, and North Carolina are where zone 7 is located. Dogwoods, Oakleaf Hydrangeas, and Contorted Hazelnut trees are common plants in this area.
Zone 8 (10° to 20°): Zone 8 plants prosper in the coastal regions of Washington state, Oregon and Northern California. This zone also spans central Texas, Georgia, Alabama, and South and North Carolina. This being the zone I live in, I know the most about this area. On my social media, most of my pictures of plants come from this zone (if you were curious!). Some of my favorite plants include Gardenias, Hydrangeas, and Peonies.
Zone 9 (20° to 30°): Zone 9 weather conditions include California, Arizona, East Texas, Louisiana, and Florida. One of my favorite plants thrives in this area, the orchid. Other Plants that do well here are Fuchsias and Eucalyptus species.
Zone 10 (30° to 40°): This area has a higher average year-round temperature than the zones discussed previously. Florida, Arizona’s Mexico border, and the Southern tip of California are the states that make up this zone. Poinsettias, Succulents, and Birds of Paradise love the heat of this region.
