Here is a modest gem that might reach four feet in ten years. It has distinctive leathery leaves that have a spongy indumentum that is yellow to olive brown in color. The flowers are soft pink to white. The plant tends to bloom at a young age and makes a compact specimen that looks good year around.
R. adenogynum is native to SE Tibet, Yunnan and Sichuan and is a member of Subsection Taliensia, a branch of the rhododendron family noted for its outstanding plant habits — mostly compact, with spongy indumentum.
This rhododendron will like well-aerated soil with good drainage, filtered sun and gentle watering, very small amounts of fertilizer on Valentine’s Day and Mother’s Day. It’s hardy for western Washington.
