One of the few Kurume azaleas from Japan that was found to be winter-hardy in western Europe. It became one of the main parents for most European obtusum-type garden azaleas. With small, single, red flowers with a compact plant habit it is a very good landscape plant. Probably a R.kiusianum and R.kaempferi hybrid, having inherited the red flowers from R.kaempferi and the smaller leaves and compact plant habit from R.kiusianum.
Produced by Hinode Nursery (日の出園) at Shinjuku, Tokyo in the Kan'ei era (1624-1644).
