Ussurian Pear (Siberian)

The Black Walnut is a slow growing, large, straight-stemmed tree with an open crown. It produces dense, very hard, edible nuts.

Black Walnut has a deeply-furrowed, black bark. Its leaves are about 1 foot long, composed of 15 - 23 slightly stalked leaflets on a moderately stout stock which provide good dappled shade.

Despite being highly valued for its edible nuts and its shade tree aesthetics, it is rare to see this tree on the prairies.

Note: Black Walnut's roots produce a substance named juglone that is toxic to some other plants. Consider this when choosing where you plant a black walnut, as you will not be able to grow tomato, potato, cabbage, eggplant, blueberry, azalea, rhododendron, lilac, red pine and apple in the surrounding area.

Note: Plant this tree once. It will not respond well to transplanting.

Note: Although self-pollinating, planting two trees significantly improves nut production.

A top CO2 absorbing species. Experts think this tree may help climate change more than others.

Ussurian Pear is the most cold hardy of all pear species. It is frequently used as a rootstock or as a pollinizer for other pear varieties. The pinkish-white flowers that bloom in the spring and the striking fall colours make it well-suited as an ornamental addition to your landscape.

Ussurian Pear can also be used for forming hedges as it tends to branch quite low.

While the Ussurian Pear is considered self-pollinating, planting with another pear variety will increase yields. Can be paired with Krazulya Pear or Beedle Pear.
