Rhododendron'White Grandeur'(Brooks Hybrid)

Brooks Hybrid Azalea, Evergreen Azalea, White Grandeur Azalea

White Grandeur (Rhododendron ‘White Grandeur’) is an evergreen azalea with white flowers. Its display arrives early in the rhododendron flowering season, with the exact timing influenced by local weather. Individual flowers measure about 3 inches across. The blossoms carry extra petals for a semi-double appearance. Wavy petal edges give the clusters additional texture. Contrasting green markings add detail within the flower faces.

The plant develops upright branching and compact branching. The dark green leaves have a glossy surface that gives the foliage a distinct presence between flowering seasons. Its low early growth makes it useful near the front of a planting where the flowers remain easy to see.

Give it acidic, humus-rich soil that stays moist and drains freely. A sheltered position with filtered light or morning sun is a useful starting point; protect the roots from prolonged drying and keep mulch clear of the stems.
