| Species | Ulmus americana |
| Cultivar | 'Nigricans' |
| Origin | Zöschener Baumschule, Germany |
The American elm cultivar Ulmus americana 'Nigricans'Dieck was cloned from a selection made from seedlings raised by the Zöschener Baumschule, Zöschen, Germany, and listed by Georg Dieck with a brief description in Haupt-catalog der Obst- und gehölzbaumschulen des ritterguts Zöschen bei Merseburg, 1885. [1]
An 'American Black Elm', "a variety of Ulmus americana of more erect habit", was marketed by Trumbull and Beebe's nursery, San Francisco, in the 1890s, along with a batch of other European elm cultivars. [2]
The tree was distinguished by its very dark green foliage. Occasionally listed as 'Nigrescens', it has caused confusion with a U. minor cultivar of that name. [3]
No specimens are known to survive.
