Rhododendron kamtschaticum is found abundantly in the 
islands and along the coasts in the neighbourhood of 
Behring Strait. It extends southwards to Sachalin and the 
north of Japan, and eastward to Banks’s Island off the coast 
of British Columbia. According to Pallas it occurs in 
muddy mountainous places, and begins to flower about the 
end of June. | 
This pretty species, which in general appearance reminds 
one of some of the Rock Roses, has been in cultivation for 
at least a hundred years, but, owing probably to the 
difficulty of its cultivation, it is still comparatively rare.
