A small tree, to 30 or 40 ft tall, with upright, spreading branches, the broad crown developing long, overhanging branchlets when older.[2] The leaves are dark green.[1] 'Drake' is also distinguished by having a bark that begins exfoliating at a relatively young age.[3]

Pests and diseases
The species and its cultivars are highly resistant, but not immune, to Dutch elm disease, and unaffected by the elm leaf beetle Xanthogaleruca luteola.[4]
Cultivation
'Drake' became the most popular form of U. parvifolia planted in the southern and western states of the United States.[5] It is considered less suitable for planting further north.[6][7] It has been described as "a poor choice as a street tree as it tends to have a low branching canopy and needs frequent pruning".[8] In Florida it is reported prone to storm damage.[8] One specimen is known to have been introduced to Europe.
