Helen Curtis Azalea

Helen Curtis Azalea (Rhododendron 'Helen Curtis')

Helen Curtis Azalea (Rhododendron 'Helen Curtis') is a compact evergreen azalea prized for its pure white, semi-double blooms and tidy, rounded form. Known for its elegant appearance and dependable performance, this variety offers refined color for foundation plantings, shaded borders, and formal landscapes. Its blooms appear in mid to late spring and often last longer than single-flowered types due to their fuller form.

Distinctive Features

'Helen Curtis' grows 2 to 3 feet tall and wide, forming a symmetrical mound of dense, evergreen foliage. In bloom, it's covered in medium-sized, snow-white flowers with layered petals and a subtle gloss that catches the light. Its deep green leaves remain attractive year-round, making this cultivar as much a structural plant as a seasonal highlight.

Growing Conditions

• Sun Exposure: Thrives in partial shade; tolerates full sun in cooler zones with adequate moisture.
• Soil: Prefers acidic, well-drained soils rich in organic material.
• Water: Moderate; keep consistently moist but not soggy.
• Humidity: Favors moderate humidity with good airflow to prevent fungal issues.
• USDA Hardiness Zones: 7 to 9

Ideal Uses

• Container plantings on patios or courtyards with dappled light
• Formal gardens where its neat shape suits structured layouts

Low Maintenance Care
