Searching Genus for Rhododendron

RHODODENDRON(RHODODENDRON)Family: ERICACEAE
A large genus of trees and shrubs, usually evergreen with showy flowers in terminal racemes

For a very helpful article by John Weagle on growing Rhododendron from seed, see:

RHODODENDRON brachycarpum var tigerstedtii3029
2.5m  Zone: -42C
Native to Korea, this is one of the hardiest Rhododendron worldwide having survived temperatures of -42C in Finland. The plant has very attractive, tropical-looking dark green, shiny foliage with trusses of white flowers. Variety tigerstedtii has longer leaves, larger white flowers, and exhibits more vigor. Because the Mustila Arboretum in Finland is central to its introduction I quote from them:

"In 1935, a Rhododendron seed batch, originating from the Kongo-San mountains in eastern-central Korea, was received in Arboretum Mustila, in SE Finland. The new material proved to be extremely hardy, but it could not be classified under any known species. In 1970, Nitzelius described and named it Rhododendron brachycarpum subsp. tigerstedtii. This Rhododendron is perhaps the most famous of the plants of the Mustila Arboretum. It was collected in 1930 in Hozan (now Pungsan), North Korea (4049'N, 12659'E, 1200 m), sent to the arboretum by the Japanese forest research institute in Korea, as Rhododendron chrysanthum (Rh. aureum), and described by the Swedish botanist Tor Nitzelius as Rhododendron brachycarpum ssp. tigerstedtii, after the introducer, Dr. C. G. Tigerstedt."

Our seed comes from a direct clone from Arboretum Mustila. The photograph is from their web site.
