About

Ulmus wallichiana Planch., the Himalayan elm, also known as the Kashmir elm and Bhutan elm, is a mountain tree ranging from central Nuristan in Afghanistan, through northern Pakistan and northern India to western Nepal at elevations of 800–3000 m. Its common name is occasionally used in error for the cherry bark elm Ulmus villosa, which is also endemic to the Kashmir, but inhabits the valleys, not the mountain slopes, and is dissimilar in appearance. The species is closely related to the wych elm U. glabra.

How to grow it

Endemic to an impoverished region with no fossil fuel resources, U. wallichiana is heavily lopped for firewood, and also for fodder, leaving it in danger of extermination in some areas. Elsewhere however, it has been deliberately planted near villages and farmhouses. Recognizing its predicament, efforts have been made in India to conserve the tree by drying the seeds and placing them in refrigerated storage. A species of considerable commercial potential, research has also been undertaken into optimal propagation methods.

The tree was first introduced to the West in the 1920s, with the arrival of a specimen at the Arnold Arboretum from Chamba, a hill station overlooking the north Indian plain. The tree soon proved eminently unsuited to the cold Boston winters and died, but not before a five-budded cutting could be sent to S. G. A. Doorenbos, Parks Director at The Hague, in 1929. Doorenbos was able to graft four of the buds, and the following year had a row of strongly growing plants.
