Looking for a tough and attractive tree that can grow almost anywhere? Look no further than the Ulmus parvifolia, also known as the Chinese Corkbark Elm, Chinese Elm, or Lacebark Elm. This deciduous or semi-deciduous tree is highly resistant to Dutch elm disease and unaffected by the Elm Leaf Beetle, making it an excellent choice for city streets, parking lots, or small planters along streets or plazas. Its bark often features attractive patches in shades of gray, green, orange, and brown, while its dark green and shiny leaves can turn yellowish to reddish purple in the fall. The Chinese Elm is also a popular choice for bonsai enthusiasts, as it has a high tolerance for pruning. Originally from northern China, Korea, and Japan, the Chinese Elm is now found on all continents except Antarctica, and is considered one of the hardiest and most splendid elms in the world. Whether you're a landscaper, gardener, or tree enthusiast, the Chinese Corkbark Elm is an outstanding plant that is sure to impress.
