Tested in the US National Elm Trial coordinated by Colorado State University, [1] Triumph averaged a survival rate of 86% after 10 years.

However, its performance in the southern United States has not impressed, and it was dismissed as "ugly" by Michael Dirr, Professor of Horticulture at the University of Georgia [3], on account of its "wild" growth and splaying branches.

In trials in the UK, Triumph was found to be the first elm cultivar to flush in spring, and the first to shed its leaves in the fall, usually by early October.

The tree grew poorly on thin soils over clay, which became very dry in summer, but excelled on floodplain alluvium subjected to brief periods of inundation in winter.

Triumph was briefly in commerce in the UK, where 180 trees were sold in 2006; several specimens were acquired for assessment by Butterfly Conservation in Hampshire.
