 Ulmus Elm Bonsai
Ulmus species and in particular Ulmus parvifolia/Chinese Elm are very often confused with Zelkova species in particular Zelkova serrata/Japanese Elm.
Zelkova are classed as a seperate genus to Ulmus as they have fruits that are unwinged as opposed to the winged friuts of Ulmus.
Ulmus parvifolia/Chinese Elm are often sold as indoor bonsai and as such are acclimatised to indoor growing conditions, however Chinese Elms are temperate trees and fully frost hardy.

 Ulmus glabra - Wych Elm   (Site not responding. Last check: 2007-10-09)
This is the most common of the native elm trees of Britain; however, in common with other Ulmus species its numbers have been decimated by Dutch elm disease - a fungus infection known to mycologists as Ophiostoma novo-ulmi, which belongs to the fungal class Ascomycetes - that entered Britain in the mid 1960s.
Leaves of Ulmus glabra are generally broadest near the apex and have 12 to 18 pairs of veins that end in pointed teeth at the edge of the leaf.
As with other elms, the upper side of the leaf is covered in stubbly bristles.

 Ohio Trees, Bulletin 700-00, Ulmus – Elm
Like other American elms, the true American elm is susceptible to the Dutch Elm disease and phloem necrosis (elm yellows) but somewhat resistant to elm-leaf beetle feeding.
During the ‘20s and ‘30s, American elm was planted almost to the exclusion of other trees, due to the incredible urban-tolerance of Ulmus americana.
The lack of diversity set U.S. cities up for the introduction of Dutch elm disease (DED) from Europe.

 Saving the American Elm   (Site not responding. Last check: 2007-10-09)
Both “Valley Forge” and “New Harmony” are purely American elms (Ulmus americana) from the northern United States which are easy for the amateur gardener to cultivate and to propagate vegetatively.
Of this much I am certain: A scientific report from 1994 asserts based on microscopic examinations that “Jefferson” is a triploid elm with 42 chromosomes, in contrast to typical American elms, which are tetraploid and have 56 chromosomes.
This clone (referenced in some reports as “clone N3487,”) was released to nurseries in 2004, after screening tests showed it to have an outstanding level of tolerance to DED.

 Ulmus parvifolia
shade tree members of the Elm Family that are resistant to Dutch Elm Disease and are of ornamental quality (Ulmus americana 'Delaware', Ulmus x 'Homestead', Ulmus x 'Pioneer', Ulmus x 'Regal', Ulmus x 'Urban', Zelkova serrata)
Lacebark Elm is the perhaps the best all-around Elm for its combination of clean foliage, fall color, and ornamental bark, while not being susceptible to Dutch Elm disease.
Ulmus parvifolia is known as an unusual Elm that has excellent ornamental bark and mixed fall color that transitions very late, and also has excellent dark green shiny Summer foliage, flowering and fruiting late in the season, and a spreading habit from co-dominate trunks and semi-pendulous branchlets that provide filtered shade.
