Azalea ‘Johanna’

Azalea ‘Johanna’

Azalea ‘Johanna’ is a striking evergreen shrub celebrated for its rich, deep red blooms that appear in mid to late spring. The vibrant flowers, with slightly ruffled edges, contrast beautifully against the plant’s dark green, glossy foliage. As the seasons change, the leaves take on a bronze-red tint in autumn and winter, providing year-round color and texture. Compact and rounded in habit, ‘Johanna’ typically grows 2 to 4 feet tall and wide, making it a versatile addition to borders, foundation plantings, or woodland gardens.

Part of the reliable Girard hybrid series, ‘Johanna’ offers exceptional cold hardiness and thrives in partially shaded environments. Its prolonged blooming period and dense growth habit make it ideal for adding structure and color to shaded or dappled-light areas. Whether used as a focal point or planted in groups for mass color, Azalea ‘Johanna’ delivers beauty, durability, and multi-season appeal.

Care Instructions

Planting:
Plant in partial shade with well-drained, acidic soil (pH 4.5–6.0). Position the root ball slightly above ground level to prevent waterlogging.

Watering:
Keep soil evenly moist but not soggy. Deep water once a week during dry spells, particularly in the first growing season.

Pruning:
Lightly prune after flowering to shape and promote new growth. Avoid heavy pruning late in the season to preserve next year’s blooms.

Pest Control:
Watch for lace bugs and spider mites. Treat infestations with horticultural oil or insecticidal soap. Encourage beneficial insects naturally.

Soil Tips:
Amend with organic matter like peat moss or pine bark to maintain acidity. Apply mulch annually to conserve moisture and insulate roots.
