Herman Research Arboretum, Absaraka, described in 2017, and released in 2021. It is notable for its burgundy fall colour, rare in elms where yellow is the norm, for its cold-hardiness, and for its "good" resistance to Dutch elm disease.

NDSU report it superior in cold-hardiness to the hybrid cultivar 'Frontier', which also has wine-coloured autumn foliage.

The cultivar has medium green leaves colouring from apricot to rich burgundy before leaf-fall. The smooth grey-brown bark begins to fissure vertically with orange tinges after the first few years of growth. Seed production is light.

Pests and diseases

Cultivation

The tree was recommended for cultivation in North Dakota, though reportedly "production numbers were lower than planned" (2021). is tolerant of high pH levels. The species does not sucker from roots.
