Pyrus ussuriensis, the Ussurian Pear, is one of the hardiest ornamental trees available for the Canadian prairies, offering exceptional four-season interest in a single, elegant package. In spring, the tree erupts in a profusion of fragrant, five-petalled white blossoms before the leaves emerge, creating a breathtaking early-season display that rivals any flowering tree in the northern landscape. The glossy, dark green foliage is attractive throughout summer, then transforms into a brilliant display of scarlet, orange, and burgundy in autumn — among the most vivid fall colour of any prairie-hardy tree. Small, hard, yellowish-green fruit follow the flowers and provide valuable late-season food for birds and wildlife. Native to northeastern Asia, this long-lived, adaptable tree has proven itself a dependable and beautiful choice for prairie yards, boulevards, and parks for generations.
