Rhododendron 'Gumpo White' blooms with big, white blossoms from April through May, which contrast attractively with the dark evergreen leaves. Once established, this exquisite evergreen Azalea is low-maintenance and undemanding. It is a low-growing, spreading cultivar that can be used as a focal point in a rockery or mass-planted at the edge of acid forests. Height: 60cm (24). Spread: 120cm (48).
