R. maddenii Reid Form
I was given this plant by the late Robert MacIntyre, who was the president of the American Rhododendron Society for a few years. Bob lived in Bandon, Oregon and he claimed that this form of Rhododendron maddenii was more hardy than any other cultivar. He said it made it through a winter that dipped to 10 degrees. Hard to believe for a maddenii, but could be. The flowers are white with a bit of pink in lax trusses of 4 or 5 florets. The plant is very handsome, making a big lush mound 5 ft tall and a bit wider in 10 years. The fragrance is heavenly!
