Hardy azaleas add color and structure to the garden and landscape—and so much more. As their name implies, hardy azaleas can handle winter temperatures that drop below 0 degrees F. Their fragrant flowers burst into bloom in late spring to early summer and attract hummingbirds and butterflies. Growing 4-6 ft. tall, these manageable shrubs are ideal for foundation plantings or growing as a flowering hedge. Azaleas grow best in an area that receives full sun to partial sun. Flowering shrubs and bushes are some of the most versatile plants to add to the landscape, and a valuable addition to any garden design.
