Siberian elm - what kind of plant is it?
Siberian elm (Ulmus Pumila Celer), also called dwarf elm is a plant native to Asia, more precisely - Syberia, as the name indicates. This majestic plant can also be encountered in Mongolia.

What does Siberian elm look like, and what are its characteristic features?
Siberian elm is a plant that can reach impressive heights – of course, if the conditions allow it. With good care, proper soil and favorable climate, it can grow up to 30 m (98.43 ft). This height is achieved after a dozen or couple of dozen years, but it’s fairly impressive nonetheless. But it’s difficult to achieve with in-yard cultivation. Trees measuring up to 2-3 meters (7-10 feet) are much more common.
Siberian elm is very characteristic for its asymmetrical habit. Interestingly enough, there are two options for its cultivation. Although in its natural habitat it’s a tree, it’s often grown as a bush in gardens. A lot depends on the variety of this species, as it determines how the branches develop.
As for the appearance of Siberian elm, the leaf shape also depends on a particular cultivar. There are two options:
- Aurescens variety has green leaves that might turn yellow in spring, and return back to normal soon after,
- Aurea variety has characteristic yellow leaves, and they last from early spring until late autumn.
