  • Description

  • Notes

Accolade® Elm (Ulmus japonica x wilsoniana’ Morton’) is a cultivar that derives from a specimen growing at the Morton Arboretum. It has arching limbs and a graceful vase shape like that of the classic American Elm. Its glossy dark green foliage changes to yellow in the fall. Heat and drought resistant. Grows 50 to 60 feet tall and 25 to 40 feet wide. A lovely shade tree, ideal for providing relief on west or south facing exposures.
Do not confuse this elm with the Siberian elm, a weedy tree with prolific seed and prone to disease. Adaptive to a variety of soil ph, even in the extremes. Fastest rate of growth with regular water in good, well drained soil, and in full sun. But avoid over-watering, as the pratice encourages shallow roots. Resistant to Dutch Elm disease and elm leaf beetle feeding.
