Quercus macrocarpa
Juglans nigra
NOT AVAILABLE THIS SEASON
(new stock expected: fall of 2026)
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.
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.
