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.^[2][6] Lines of Bosque and Allee in North Robinson Avenue and North Harvey Avenue, Oklahoma City, flank the Oklahoma City National Memorial.^[1]
