Nigricans (American elm cultivar)

From Wikipedia, the free encyclopedia

The American Elm U. americana cultivar Nigricans was a selection made from seedlings raised by the Zoschener Baumschule, Germany, at the end of the 19th century. The tree was distinguished by its very dark green foliage. The tree was occasionally listed as U. americana "Nigrescens", causing confusion with a U. glabra cultivar of that name.
