WILD BLACK CHERRY
R. W. Smith
A common tree of fencerows and borders of fields and forests, almost anywhere that birds have deposited the seeds; can be very scrubby in rocky ground or dry open jack pine or aspen savanna or a tall tree attaining considerable size in rich hardwoods.
There is often a strip of pubescence, usually rust-colored, along the midrib on the underside of the leaves, although sometimes there are no hairs at all. See also comments under P. virginiana.
Several species of Prunus, especially P. serotina, are known as stock-poisoning plants, because of their cyanogenic glycosides that produce dangerous amounts of hydrogen cyanide, particularly in the succulent young leaves and slightly wilted ones and in the pits, which may fatally poison children.
The only Keweenaw Co. collection is an 1884 one by Farwell lacking locality data; the tree is otherwise not known from either Houghton or Keweenaw Cos., and the Farwell collection may be mis-labeled.
