Rhododendron Yaku Angel

Yaku Angel (Rhododendron ‘Yaku Angel’) is an evergreen rhododendron with white flowers. Its display arrives near the middle of the rhododendron flowering season, with the exact timing influenced by local weather. Individual flowers measure about 2 inches across. The blooms open with a bell-like outline. Clusters commonly carry about 13-17 blossoms. Contrasting brown markings add detail within the flower faces.

The plant develops a crown that becomes wider than tall. A fine covering beneath the leaves adds detail to the foliage at close range. 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.
