Rhododendron Big Deal

Big Deal Rhododendron Big Deal

Big Deal (Rhododendron ‘Big Deal’) is an evergreen rhododendron with yellow flowers. Its display arrives through the middle and later part of the rhododendron flowering season, with the exact timing influenced by local weather. Individual flowers measure about 3 inches across. The flower tubes widen into flared faces that display the color clearly. Wavy petal edges give the clusters additional texture. Contrasting yellow markings add detail within the flower faces.

The plant develops outward-spreading growth and a dense crown. Its foliage is retained through winter, keeping a leafy framework 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.
