In the southern most parts of the United States azaleas and rhododendrons are blooming or will shortly. Azaleas and rhododendrons are commonly used in landscapes through most of the United States. From a taxonomic point of view, azaleas and rhododendrons are classified together in the genus rhododendrons. Azalea is commonly used as a native deciduous species. Rhododendron often refers to species with large, evergreen, leathery leaves. Some suggestions for planting rhododendrons includes:

• Plant on a site sloping north or east to protect them from drying winds from the south and west.
• Plant rhododendrons where they will have wind protection.
• Plant in well drained soils
• Many people think of azaleas and rhododendrons as shade lovers, yet dense shade can cause decline. Filtered sunlight is best but morning sun with afternoon shade is satisfactory.
