Black walnut
NativeJuglans nigra
Walnut (Juglandaceae) · Walnut · 70–90 ft
Knowing it
Dark furrowed bark, long compound leaves, and the round green-husked nuts that stain everything. Rich bottoms and slopes statewide; Missouri leads the nation in wild nut harvest.
What a tree company sees
Valuable timber: a straight trunk can be worth selling rather than chipping. Roots release juglone, which kills tomatoes and some shrubs beneath it. Thousand cankers disease is a watch item.
