Japanese Tree Lilac vs Black Walnut

Syringa reticulata

Juglans nigra

Japanese Tree Lilac
no image

Japanese Tree Lilac is an attractive heavy-flowering lilac with fragrant white blossoms. It can be pruned to a single stem or grown as a multi-stemmed shrub.

Japanese Tree Lilac's dark reddish-brown bark peels as the tree ages, creating visual appeal for any yard, especially in the winter.

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.
