Manchurian Walnut
Bur Oak

Manchurian Walnut is a large, broad and often multi-stemmed tree with ornamental qualities. This tree produces large, thick-shelled nuts that ripen in the fall. These edible walnuts are reportedly difficult to crack open. They are useful for attracting wildlife, especially squirrels.

The Manchurian Walnut contains and exudes much lesser quantities of allelopathic compounds, such as juglone (common to walnuts), that may prevent or impair growth of nearby plants. Therefore, it is commonly embraced as a safe walnut to plant.

There are reports of rare this species surviving winters to -45C with specimens growing and thriving in Alaska and Edmonton.

There is no regular supply of this species. It is rare and not produced each year.

Bur Oak has a wide distribution but is one of the only oaks that will grow well on the prairies. Bur Oak produces deeply lobed, dark green leaves that turn golden yellow to brown in the fall.

Its acorns are round and half enclosed by a mossy fringed cup.

Although slower growing, this long lived tree eventually becomes a popular large ornamental tree for driveways, parks, and the front of industrial buildings. Popular as a memorial or dedication tree.

Note: Most Oak species can be considered toxic for many animals.
