Tristis Poplar

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.

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.
