Rhododendron brachycarpum var. tigerstedtii

In 1931 Mustila Arboretum acquired some seeds of Rhododendron aureum from the Pungsan Mountains of North Korea. But the seedlings turned out to be something quite different: a previously poorly-known Korean form of the Japanese rhododendron (R. brachycarpum), a sturdy-growth variety with large leaves and flowers that in 1970 was named Rhododendron brachycarpum subsp. tigerstedtii and subsequently known in Finland as the Mustila Rhododendron.
