President Roosevelt' is an unusual Rhododendron in that it has variegated foliage.
The leaves are green around the outside and yellow in the middle.
The abundant flowers are also two-tone.
They have a white centre and wide margins of bright reddish-pink.
From a distance they appear to be red.
The growth habit can be a bit straggly if not lightly pruned.
Picking the flowers for a vase is always a good way to prune plants.
This variety usually grows to approximately 1.5M.
