---|---|
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]
Description
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]
Cultivation
No specimens are known to survive.
