Native of the Caucasus at sub-alpine elevations; introduced to Kew from Tiflis in 1897 and put into commerce by Späth of Berlin in 1906. It makes a handsome bush with alder-like leaves and is very striking in winter with its glossy, pale brown stems and large buds. The leaves usually die off a light yellow. The largest specimen recorded grows at Mount Usher in Co. Wicklow, Eire; it is 15 ft high and 27 ft across (1966). The specimen at Kew, referred to in the Botanical Magazine under the number cited, died in 1959; it was about 12 ft high and 15 ft across.
