The intense blue-violet color is spectacular, and very unusual in such a hardy rhododendron.

Blooms early (April in eastern Massachusetts).

The breeder recommends siting where it's protected from winter sun and winds in Z6.

Absolutely stunning in Bloom, its as close to true blue as it gets. Not long blooming but when it does (very reliable) it's a show stopper. Be careful not to drown it when getting it established. Once established it's very rugged.
