Japanese gardeners have been growing azaleas for centuries, prizing them for their trumpet-shaped spring flowers in shades of pink, yellow, salmon, red, violet, and white. Modern hybridizers have developed a reblooming azalea, so you do not have to wait for another spring to enjoy the floral feast of this perennial shrub. Give your azalea shrub a site in partial shade, and amend the soil with organic materials like compost or leaf mold to increase acidity. Azaleas like regular moisture, but they will rot in wet winter soils.
