Percy Wiseman Rhododendron

The Story

Plant Bio

A compact, mounding, large-leaf evergreen rhododendron known for its dense habit and beautiful, uniquely colored flowers.

‘Percy Wiseman’ is celebrated for its remarkable flower trusses that change color. The blooms open a peachy-pink and gradually fade to a creamy white with a yellow throat, creating a multi-toned effect on the plant.

Uses & Benefits:

The unique, color-changing flowers create a beautiful, subtle, multi-toned effect that is highly prized. Its compact, dense habit makes it a well-behaved and attractive shrub year-round.

Its manageable size makes it suitable for smaller gardens, foundation plantings, and mixed borders where a large rhododendron would be overwhelming.

The flowers provide nectar for bees, hummingbirds, and other pollinators. The evergreen foliage offers winter cover for small birds.
