R. arboreum 'Leonardslee'
From the Leonardslee Estate in Great Britain, this form of R. arboreum is quite stunning. The flowers are a bright white with a florescent pink picotee edge to each flower. The plant grows large with dark-green leaves the have a shiny silver indumentum on the back sides of the leaves. They hang quite steeply on the plant, and this is quite normal, but until you get used to it, it may alarm some people. Rare.
