When you are deciding what plants to choose for your hedge, you need to be sure the plants you choose will grow well in your planting zone. Question: What is a planting zone?
Answer: The country is divided into different growth zones to enable you to choose the flowers, plants, and vegetables, which will grow best in your area. Zones provide timelines for planting because since areas of the country warm up at different times.
The United States has eleven gardening zones. They range from coldest at number one to eleven, which includes the most Southern area of the States. Here is a rundown of the zones. Temperatures quoted are the lowest temperatures reached in that area.
Zone 1 has a temperature that drops to 50 degrees below zero; this will include the Northern part of Alaska and of course upper Canada.
Zone 2 is slightly south of Zone 1 and will include the lower parts of Alaska and the Northern portion of Minnesota. The lowest temperature can get to 40 to 50 below Fahrenheit in this zone.
Zone 3 includes cities such as International Falls, Minnesota and Sydney, Montana. The average lowest temperature is 30 to 40 degrees below.
Zone 4 has an average lowest temperature of 20 to 30 degrees below and is found in the upper portions of Minnesota, Nebraska, and Montana.
Zone 5 with the average lowest temperature of 10 to 20 degrees below zero includes the states of Iowa, upper portions of Illinois and Missouri.
Zone 6 includes the lower portions of Illinois and the Midwest states going all the way down to Branson Missouri and Nashville Tennessee. Temperature in this area generally do not drop to more than 10 below zero and then only rarely and for short periods.
Zone 7 takes a swing through Georgia, Arkansas, and Virginia. Their average low temperature is 0 to 10 degrees.
Zone 8 includes parts of Texas to the upper portions of Florida. Temperatures in each zone increase ten degrees each time you go to a higher zone level.
Zone 9 includes the lower portions of Texas and Florida with temperatures rarely getting below 20 degrees.
Zone 10 includes the lowest portion of Florida as well as the southern part of California.
Zone 11 would encompass the state of Hawaii.
Some shrubs are good for nearly all zones; they are listed below. I will give these to you in their commonly known names, not their botanical names. The list below is just a few of the shrubs and plants. Many more can be found in stores that specialize in plants.
- Canert Juniper
Privets (except for zone 4)
Arrow wood viburnum

As you can see, you have a large variety of shrubs and hedge plants that will grow in any area. For information that is more precise, contact your local extension office. They are always glad to answer questions. They can tell you for certain what zone you are in and give advice on what type of hedge you can use in your climate zone.
You will also find very good information on the Internet. A few good sites available online are:
National Arboretum – USDA Plant Hardiness Zone Map
American Horticultural Society – Heat Zone Map
These sites have more information on not only the climate zone you live in but also give you detailed information on what type of plants are good for your zone.
