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.
