Report an issue with this species

Ulmus 'Accolade' is a horticultural hybrid elm known for its gracefully-arching branches, vibrant green foliage, and attractive yellow fall colors. Developed for resistance to Dutch Elm Disease, Elm Yellows, and Elm Leaf Beetle, it has proven highly successful in trials and is widely planted in urban settings as an alternative to the American Elm. While drought-tolerant, it can be susceptible to wetwood and phloem necrosis.
