American elm
Ulmus americana 'Lewis & Clark' PRAIRIE EXPEDITION
American elm (Ulmus americana 'Lewis & Clark' Prairie Expedition) is a stunning deciduous tree with a mature height of 50-60 feet tall. It develops a dignified, asymmetrical shape and turns a lovely golden yellow color in the fall. The 3-4” ovate leaves are dark green, with a light downy texture beneath, and have a gentle arching vase shape. The species is notable for its tolerance of drought, wet and cold climates, and resistance to Dutch elm disease. It adapts to a range of soils from clay to sandy, making it a versatile choice for urban landscapes. Its rapid growth rate and beauty make the American elm a popular choice for shade, street, and park trees.
