Clusters of double pink blooms cover Azalea x 'Girard Roberta' in spring, creating a showy display against its glossy green foliage. This evergreen shrub maintains year-round interest, with its leaves turning a deeper shade in cooler months. Reaching 2 to 4 feet tall and 3 to 5 feet wide, it forms a compact and mounding shape, making it an excellent choice for foundation plantings, woodland gardens, or border accents. Hardy in zones 6 to 9, this azalea provides reliable color in cooler climates.
A low-maintenance selection, Girard's Roberta resists cold damage better than many other azaleas. Its dense, multi-stemmed habit works well for naturalized plantings or mass groupings in shaded areas. While not fragrant, its flowers attract pollinators and brighten up partial sun locations. This variety thrives in acidic soil and pairs well with ferns, hydrangeas, and other shade-loving plants. It also performs well in containers, adding seasonal color to patios and entryways.
Girard's Roberta Evergreen Azalea Care
Plant in well-drained, acidic soil rich in organic matter. This azalea prefers dappled sunlight or morning sun with afternoon shade, especially in hotter climates. Regular watering is necessary, especially during the first growing season, to establish a strong root system. Apply an acid-forming fertilizer in early spring to encourage lush growth and abundant blooms.
Minimal pruning is needed. If shaping is desired, trim immediately after flowering to avoid removing next season’s buds. Removing spent blooms can encourage a tidier appearance. A layer of mulch around the base helps retain moisture and regulate soil temperature.
Girard's Roberta Evergreen Azalea Spacing
For hedges or mass plantings, space plants 3 feet apart. When planting as a single specimen, allow at least 4 feet of space for full development. If growing in a container, choose one at least 16 inches wide to accommodate the root system.

?
"Blooms on" tells you which stems produce flowers, which decides when it's safe to prune.
- New Wood: Flowers form on stems that grow this season. Prune in late winter or early spring without losing blooms.
- Old Wood: Flower buds form on last year's stems. Prune right after flowering. Pruning in fall or early spring removes next year's blooms.
- Both New and Old Wood: Blooms on last year's stems and again on new growth, so it flowers even after a hard winter or a mistimed pruning. Prune lightly after the first flush of blooms.
