'Jacan' develops an attractive rounded crown form typical of the species; the foliage turns a deep red in autumn [1].
The tree is moderately resistant to Dutch elm disease, and elm leaf beetle Xanthogaleruca luteola [2][2]. The tree's foliage was adjudged "resistant" to Black Spot by the Plant Diagnostic Clinic of the University of Missouri [3].
'Jacan' was introduced to the UK from Canada in the early 1980s, but has not been widely planted on either side of the Atlantic. It is not known to have been introduced to Australasia.
