Rhododendron 'Cunningham’s White': Bright White Spring Trusses for Classic Shade Gardens

Rhododendron 'Cunningham’s White' is a timeless, dependable evergreen rhododendron that brings a fresh, luminous look to part-shade gardens in spring.

The deep green evergreen foliage stays handsome year-round, giving the garden structure long after flowering. Reliable and easy to design with, it’s a go-to choice when you want spring colour that feels crisp and classic.

Water regularly during establishment and during dry spells, especially through summer heat. Prune only lightly right after flowering, removing spent trusses and any winter-damaged growth, and avoid heavy pruning that can reduce next year’s bloom. Shelter from harsh winter wind where possible to protect foliage and flower buds.
