How Can We Help?
The Chinese Elm cultivar Ulmus parvifolia 'Drake' was marketed by the Monrovia Nursery of Azusa, California from 1952 to 1953.
Description
The tree has upright, spreading branches bearing dark-green leaves.[1] 'Drake' is also distinguished by having a bark that begins exfoliating at a relatively young age [1].
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.[2]
Cultivation
'Drake' became the most popular form of U. parvifolia planted in the southern and western states of the United States.[3] One specimen is known to have been introduced to Europe.
