Tristis Poplar is a large deciduous tree. It is cold hardy, disease resistant, and relatively drought tolerant. Tristis Poplar loses its leaves later in the year than other Poplars, making it a great ornamental tree in fall.

It's known for its strongly scented balsamic buds and yellow foliage in autumn. Because of its size, Tristis Poplar is most suitable for large properties and will help prevent wind erosion.

Tristis Poplar is slower-growing than many newer hybrids, for a longer useful lifespan. Tristis grows especially well in the southern prairies due to its resistance to cold dry winds.

The Black Walnut is a slow growing, large, straight-stemmed and high value timber tree with an open crown. It produces a dense, very hard, edible nut. The root system usually includes a deep tap-root and several wide-spreading and deeply set lateral roots.

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.

Its 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.

Despite being highly valued for its edible nuts, high value timber, and its shade tree aesthetics, it is rare to see this tree on the prairies. Plant this tree once when it is young as it does not respond well to transplanting.
