R. 'Unique' variegated form

We were given this variegated form of the rhododendron 'Unique' by the Thompson Nursery in Oregon. Every leaf is dark-green with a bright yellow edging. The plant grows slower than R. 'Unique', but the flowers are much the same, white flushed pink with a bit of yellow in the throat. Tropical colors! The variegation makes the plant stand out in the landscape. Hardy to zone 6b.
