Lacebark Elm Scientific Name: Ulmus Parvifolia Order
Common Name: Lacebark Elm Scientific Name: Ulmus parvifolia Order: Urticales Family: Ulmaceae Description The leaf arrangement of the lacebark elm (also known as Chinese elm) is alternate. Each leaf is oval with a serrate margin. Typical leaf coloration is leathery green, with purple, red, and yellow in the fall. The tree grows to a height of 40 to 50 feet with a spread of 35 to 50 feet. The bark is thin, thus giving rise to its common name as the lacebark elm. The tree produces a hard and dry fruit that brown and typically less than .5 inches in length. The root system contains a number of large-diameter members located close to the surface, and can grow for a long distance from the trunk. Growth Habit Lacebark elm is deciduous, but has been known to be evergreen in the southern extent of its range. The trees typically have a single trunk, although some have split trunks. They typically grow to a mature height of over 10 – 12 feet. It produces a bloom from late summer to fall which is yellow to green in color. A fruit is set in the fall. Hardiness Zone(s) The USDA hardiness zones for this plant are 5B through 10A. Culture Lacebark elm has no demanding culture for its habitat, and is considered to be quite hardy. It grows well in part shade as well as full sun, and has a high drought tolerance. For habitats near ocean, it has a moderate air-borne salt tolerance. For soils, it tolerates nearly all types, from clay, to sand, to loam. -
Intervascular Pit Membranes with a Torus Was Investigated in Steven Jansen Juvenile Wood Samples of 19 Species of Ulmus and Seven Related Genera

By contrast, bordered Accepted: 15 March 2004 pit pairs with round to oval pit apertures and indistinct pit canals that connected doi: 10.1111/j.1469-8137.2004.01097.x narrow (incomplete) vessel elements or vascular tracheids with distinct helical thick- enings were frequently characterized by a torus in ring-porous wood samples of Ulmus and Zelkova. Tori were lacking in diffuse-porous species of Ampelocera, Aphananthe, Gironniera, Holoptelea, Phyllostylon, Trema and Ulmus. • Our observations suggest that tori are more common in cold temperate climates than in warm (sub)tropical environments. This may indicate that narrow tracheary elements with torus-bearing pit membranes provide an auxiliary conducting system which is of low conductivity, but offers greater resistance to freezing-induced cavitation. -

Classic Lacebark Elm
Athena ‘Emer I’ Classic Lacebark Elm Lineage Ulmus parvifolia (Chinese elm, Lacebark elm, Drake elm). Also known as ‘Emerald Isle’. PP7551 Introduced in 1989 (Dave’s Garden, 2011). Tree Form A medium-sized tree with a broad rounded canopy, often with a trunk that forks resulting in a vase shape similar to that of the American elm (Floridata, updated 11/18/2010). Tree size, leaf size and growth rate half of that of the American elm, and they are often planted as a single tree (Warren, 2000). Height: 30 to 40 feet Width: 35 to 45, up to 60 foot wide crown spread (Delmar Learning, undated; UConn, undated)) Foliage Dark green in summer, leathery, almost black; bronze to bronze-brown in fall (Cornell, undated). Leaves simple, 1 to 2 inches long, but half as wide. Ovate, margins rounded to serrate (Delmar Learning, undated). Late deciduous, almost evergreen in mild climates (Floridata, 2010). Culture NA Disease and Insect Information Literature (Dutch elm disease studies, insect resistance assessments, etc.): Resistant to Dutch Elm Disease (DED), phloem necrosis and Elm Leaf Beetles (Delmar Learning, undated). It resists DED and shows very good performance under dry conditions (UConn, undated). Completely immune to Gypsy Moth, and only 10% of the leaf tissue was consumed by Japanese Beetle, the lowest of all the asian elms tested in a no-choice study (Paluch et al., 2006). When the Japanese Beetles were given a choice of species they did not feed on the U. parvifolia at all (Paluch et al., 2006). In an earlier similar study, U. parvifolia was the most resistant of all cultivars and hybrids to the Japanese Beetle (Miller et al., 1999). -
ELMS for NEBRASKA Justin Evertson & Bob Henrickson, NSA 2011
THE NEBRASKA STATEWIDE ARBORETUM PRESENTS ELMS FOR NEBRASKA Justin Evertson & Bob Henrickson, NSA 2011. For more plant information, visit arboretum.unl.edu or retreenbraska.unl.edu. Elms are majestic trees with a tall, arching habit that makes them useful for providing shade along streets, parks, and backyards. Elms are also relatively tolerant of poor soils and extreme weather. While Dutch elm disease has eliminated much of the old elm population in Nebraska, many new hybrids and cultivars show promising resistance and are making the elm o.k. to plant again. Elm Species 1. American Elm - Ulmus americana: disease resistant varieties include ‘Princeton’, ‘Jefferson’, ‘Valley Forge’ and ‘New Harmony’; 50-70’x50-70’. Note that ‘Valley Forge’ has poor branch angles and shows a tendency to break apart in wind storms. 2. Japanese Elm - Ulmus davidiana var. japonica (very cold tolerant; rounded habit; glossy green; 45’x 45’) 3. Lacebark Elm - Ulmus parvifolia (distinctive mottled bark; small glossy leaves; 35’x 25’) 4. Rock Elm - Ulmus thomasii (distinctive corky stems; upright habit; DED resistance in west; 50-60’x 30-40’) Elm Hybrids and Cultivars 5. ‘Accolade’ - looks like American elm; Morton Arboretum hybrid of U. japonica and U. wilsoniana; 50’x 40’. 6. ‘Cathedral’ - tough and adaptable; developed in Wisconsin; U. pumila x U. japonica; 40-50’x 40-50’. 7. ‘Discovery’ is a promising U. davidiana cultivar selected from Manitoba Canada; 45-50’x40-45’. 8. ‘Emerald Sunshine’ is a cultivar of Ulmus propinqua known for clean habit and yellow fall color; 30-40’. 9. ‘Frontier’ - smaller, glossy leaves; lacy bark pattern; purple fall color; U. -
Disease Resistant Elm Selections Bruce R
RESEARCH LABORATORY TECHNICAL REPORT Disease Resistant Elm Selections Bruce R. Fraedrich, PhD, Plant Pathology Many hybrids and selections of Asian elm that have reliable resistance to Dutch elm disease (DED) are available for landscape planting. In addition to disease resistance, these elms tolerate urban stress and are adapted to a wide range of soil conditions. These selections are suitable for routine planting in areas where they are adapted to the climate. Descriptions in this report are based primarily on performance of trees growing in the arboretum at the Bartlett Tree Research Laboratories in Charlotte, North Carolina (Zone 8). Accolade Elm in Northern Plains States where low temperatures and low rainfall limit successful use of other cultivars. Ulmus davidiana var. japonica ‘Morton’ A selection of Japanese elm, Accolade elm exhibits Commendation Elm strong resistance to DED and is expected to be resistant to elm yellows. This selection is a favored host Ulmus ‘Morton Stalwart’ of Japanese beetle which can cause defoliation in years A hybrid between U. carpinifolia, U. pumila and U. with heavy outbreaks. Accolade grows rapidly and davidiana var. japonica, Commendation has the has a vase shape with a mature height of 60 feet. It has fastest growth of any of the Morton Arboretum been planted extensively in many Midwestern cities introductions. This cultivar has an upright, vase shape (zone 4). Danada Charm (Ulmus ‘Morton Red Tip’) is but has a distinctively wider crown spread than an open pollinated selection from Accolade and has Accolade or Triumph. The leaves are larger than most similar habit and appearance. Danada Charm does hybrid elms and approach the same size as American not grow as rapidly as Accolade or Triumph in elm. -
