Once highly prized shade trees, elms have fallen on hard times. Dutch elm disease (spread by a bark beetle) has killed millions of American elms in North America and can attack most other elm species. Many of the larger elms are appealing fare for various types of beetles, leafhoppers, aphids, and scale, making them time consuming to care for, messy, or both.Ulmus hybrids
Many institutions havebeen carrying on breedingexperiments involving variouselms to produce trees resistantto Dutch elm disease. Amongthem, ‘Accolade’ has the besttrack record so far; it grows to70 ft. tall and 60 ft. wide, witharching limbs and a vase shapemuch like that of American elm.‘Danada Charm’ has a similarsize and shape but is ganglierin youth. ‘Frontier’, just 40 ft.tall and 30 ft. wide, featuresreddish purple leaves in fall.‘Homestead’, to 55 ft. tall and35 ft. wide, has a symmetricaloval to pyramidal form. ‘Patriot’forms a narrow vase shape to50 ft. tall and half as wide. ‘Triumph’grows 55 ft. tall, 50 ft.wide; it forms an upright ovalwith a strong central leader.
