Azaleas, part of the Rhododendron genus, range from small ground cover plants to very large shrubs, according to Floridata, with more than 3,000 species of the plant in the United States. However, different species grow in different zones.
Geography
According to Floridata, azaleas grow best in USDA hardiness zones 4 through 9. However, if you live in zone 4, choose an evergreen variety that can handle the cooler weather. This means that some type of azalea can grow in all 50 states.
Identification
According to the Demesne gardening website, azaleas like to grow in regions that are relatively humid with moderate climates. However, since there are so many different cultivars, finding the right one to suit your region should not be a challenge.
Considerations
Deciduous cultivars of azaleas are more sensitive to heat than evergreen varieties, according to the Azalea Society of America. However, azaleas are very adaptable plants and can survive in extremes.
