Gumpo White Azalea

Gumpo White Azalea (Rhododendron 'Gumpo White')

Gumpo White Azalea (Rhododendron 'Gumpo White') is a compact, late-blooming evergreen azalea celebrated for its crisp white flowers and low-growing habit. Part of the Satsuki hybrid group, this cultivar blooms in early summer, offering elegant color when most azaleas have already finished flowering. Its fine texture, controlled size, and reliable form make it an excellent choice for edging, small-space gardens, and foundation plantings where subtle beauty and structure are appreciated.

Distinctive Features

'Gumpo White' grows slowly to just 1 to 2 feet tall and 2 to 3 feet wide, forming a dense, spreading mound of small, dark green leaves. In June, it produces semi-double white flowers with faint pink or green markings, which vary slightly by climate and soil conditions. The blooms sit just above the foliage, creating a clean, carpet-like effect. This refined aesthetic, combined with year-round foliage, makes it a go-to option for formal or minimalist garden designs.

• Soil: Requires acidic, well-drained soil enriched with organic matter.
• Water: Moderate; prefers consistent moisture without waterlogging.
• Humidity: Adapts well to humid environments when airflow is adequate.
