Ulmus parvifolia 'UPMTF' (selling name Bosque) is a Chinese Elm cultivar that was found in a field at Moon's Tree Farm, Atlanta, Georgia, in 1993 and raised by Moon's Tree Farm nursery. It was patented in 2000. It is notable for its upright ascending branches. [2]
Rarely exceeding 6 metres (20 ft) in height, Bosque has a single central leader and strong ascending branches forming a pyramidal crown. The leaves are a lustrous dark green, turning yellow to orange in autumn. The mottled bark ranges from greyish orange to greyish brown. The tree is reputed to be very fast growing. [3] [2]
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]
An avenue of Bosque lines Purdue Mall, Purdue University, West Lafayette, Indiana. [5] Bosque lines the north side of Jackson Avenue, Corvallis, Oregon, east of 9th Street.
