Rhododendron Edward Rand

Edward S. Rand Catawba Rhododendron

Edward S. Rand (Rhododendron ‘Edward S. Rand’) is an evergreen rhododendron with red flowers. Its display arrives near the middle of the rhododendron flowering season, with the exact timing influenced by local weather. Individual flowers measure about 2⅛ inches across. The blooms open with a bell-like outline. Clusters commonly carry about 20 blossoms. Contrasting green markings add detail within the flower faces.

The plant develops upright branching. Its foliage is retained through winter, keeping a leafy framework between flowering seasons. Allow space for the branches to develop without crowding nearby plants or paths.

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.
