The name azalea, which is not a technical term, refers to those popular shrubs that are part of the enormous Rhododendron genus. They generally have smaller, less leathery leaves than other rhododendron and have flowers spread evenly all over the bush, rather than in trusses. Sizes range from under a foot to six or more feet tall. Flowers bloom in spring in jewel colors of pink, red, rose, purple, magenta, and white. Some types are deciduous, some evergreen.
How to grow: Plant azaleas in rich, well-drained, highly acidic soil in full sun or partial shade. Blooming will be more generous in sun. Prune for shape after flowers have finished blooming. Remove seedpods to direct energy back to the plant and away from seed formation.
Uses: Used mainly in shrub borders and as foundation plantings, azaleas also make good potted plants.
Related varieties: Azaleas come in a great variety of sizes, shapes, and levels of hardiness. Check local suppliers for types that do well in your region.
