Black Walnut

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.

Gray dogwood is a thicket-forming, deciduous shrub with greenish-white blossoms in open, terminal clusters. Young twigs are red and the fruit pedicels remain conspicuously red into late fall and early winter.

Fruit itself is a white, 1/4 in. drupe that usually does not remain on the shrub for long.

Great for naturalizing wild areas, this shrub attracts birds and other wildlife.
