Quick Overview:

Cunningham’s White Rhododendron has truly stood the test of time. When Andrew Jackson was in the White House and Earl Grey was the Prime Minister of the U.K., this celebrated evergreen accent was introduced. It has been loved ever since. Because of its hardiness and many other fine attributes, it has been used in hybridization perhaps more than any other Rhododendron. It is also a superb plant in its own right. A profuse and reliable bloomer, its pristine white blossoms are pure joy in spring. During the rest of the year, it will look sharp in your foundation beds, patio area, or woodland garden. A classic!


Best grown in acidic, humusy, organically rich, medium moisture, moisture-retentive but well-drained soils in part shade to full shade. Prefers a sun dappled shade. Plant in a location protected from strong winter winds. Good soil drainage is essential (doesn’t like “wet feet”). Poor drainage inevitably leads to root rot, therefore raised beds/plantings should be considered in heavy clay soils. Shallow, fibrous root systems (do not cultivate around plants) will benefit greatly from a mulch (e.g., wood chips, bark or pine needles) to help retain moisture and stabilize soil temperatures. Roots must never be allowed to dry out. Acidify soils as needed. Clip off spent flower clusters immediately after bloom as practicable.
