With Azalea × 'Karen' (Gable Azalea 'Karen'), you get a compact, dependable evergreen azalea that lights up spring with generous clusters of lavender-pink flowers. Its small, glossy leaves hold well through the seasons and may take on rich burgundy tones in cool weather, giving you color beyond bloom time.
Plant your azalea where it gets morning sun and afternoon shade, or bright dappled light. In cooler northern areas it can handle more sun, but hot afternoon sun can stress foliage. A spot sheltered from drying winds helps it look its best through winter and early spring.
Give it the soil it loves: acidic and humus-rich, moist but well-drained. Work in organic matter at planting time and keep a mulch layer (pine needles, bark, or shredded leaves) over the shallow roots to conserve moisture and moderate soil temperature. Water during dry spells, especially the first year, and avoid soggy conditions that can lead to root issues.
At maturity it typically stays in the 36-48 inch height range with a 36-48 inch spread, making it easy to use in foundation plantings, mixed shrub borders, woodland edges, and shade gardens. Prune only as needed and do it right after flowering so you do not remove next year's buds. If your soil tends to run neutral or alkaline, plan to manage pH and use azalea-friendly amendments so the plant can take up nutrients properly.
