This shrub is new on the market. The mother species of Birch-leaved Spirea is mostly native to Japan and northeast Asia and the cultivar of 'Tor' was taken from Asian stock. The name comes from the Gaelic word of "torr" that means mound or hill. 'Tor' is a little more compact growing than the Asian Birchleaf Spoirea mother species. (There is an American variety, S. betulifolia corymbosea that is rare and found wild in a few spots in the eastern US from Pennsylvania down to northern Alabama & Georgia. There is another American variety of S. betulifolia lucida, the Western Shiny Birchleaf Spirea that is shorter of 1/2 to 2 feet high and native to southwest Canada and from Wahington & Oregon into Minnesota.)
