Japanese Zelkova (Zelkova serrata) Japanese Zelkova trees are handsome trees in the Elm family, that were originally thought to be a possible replacement for the American elm tree which were lost due to Dutch elm disease back in the 1950’s and 1960’s. They are resistant to not only Dutch elm disease, but also elm leaf beetles and Japanese beetles. They should be planted in full sun are very tolerant of a wide variety of soil conditions and are particularly drought tolerant once established, thus making them great tough urban trees. They are often planted as street trees in cities. They are also suitable for planting in residential yards and residential streets, parks, and other large areas. Zelkovas have an interesting vase-shaped growth habit and typically will grow 50-80’ in height. They have dark green leaves in the summer and typically have a yellow-orange-brownish fall color. They also have an attractive bark and when mature will develop an exfoliating bark not unlike Chinese elms. There are two particular cultivars or varieties of Japanese Zelkovas that should be readily available in our area. The ‘Green Vase’ Japanese Zelkova is a highly recommended cultivar that is a very vigorous, fast- grower with the vase-shaped upright arching branches. This one grows 60-70’ and gets 40-50’ wide. There is a narrower form of Japanese Zelkova called ‘Mushashino’ that has a narrower columnar vase- shaped growth habit that is better suited than ‘Green Vase’ to tighter more restricted areas. It grows to a height or 45’ and only gets about 15’ wide. The Mushashino’ Japanese Zelkova also has a yellow fall color. .

Department of Planning and Zoning Subject: Howard County Landscape Manual Updates: Recommended Street Tree List (Appendix B) and Recommended Plant List (Appendix C) - Effective July 1, 2010 To: DLD Review Staff Homebuilders Committee From: Kent Sheubrooks, Acting Chief Division of Land Development Date: July 1, 2010 Purpose: The purpose of this policy memorandum is to update the Recommended Plant Lists presently contained in the Landscape Manual. The plant lists were created for the first edition of the Manual in 1993 before information was available about invasive qualities of certain recommended plants contained in those lists (Norway Maple, Bradford Pear, etc.). Additionally, diseases and pests have made some other plants undesirable (Ash, Austrian Pine, etc.). The Howard County General Plan 2000 and subsequent environmental and community planning publications such as the Route 1 and Route 40 Manuals and the Green Neighborhood Design Guidelines have promoted the desirability of using native plants in landscape plantings. Therefore, this policy seeks to update the Recommended Plant Lists by identifying invasive plant species and disease or pest ridden plants for their removal and prohibition from further planting in Howard County and to add other available native plants which have desirable characteristics for street tree or general landscape use for inclusion on the Recommended Plant Lists. Please note that a comprehensive review of the street tree and landscape tree lists were conducted for the purpose of this update, however, only

Predicting the Areas of Suitable Distribution for Zelkova Serrata in China Under Climate Change
sustainability Article Predicting the Areas of Suitable Distribution for Zelkova serrata in China under Climate Change Chunyan Cao 1 and Jun Tao 2,* 1 College of Horticultural Science and Technology, Suzhou Polytechnic Institute of Agriculture, Suzhou 215008, China; [email protected] 2 College of Horticulture and Plant Protection, Yangzhou University, Yangzhou 225009, China * Correspondence: [email protected]; Tel.: +86-0514-8799-7219 Abstract: Predicting the geographic distribution of a species together with its response to climate change is of great significance for biodiversity conservation and ecosystem sustainable development. Zelkova serrata is an excellent shelterbelt tree species that is used for soil and water conservation due to the fact of its well-developed root system, strong soil fixation, and wind resistance. However, the wild germplasm resources of Z. serrata have been increasingly depleted due to the fact of its weak ability to regenerate naturally and the unprecedented damage humans have caused to the natural habitats. The present work using Maxent aimed to model the current potential distribution of this species as well as in the future, assess how various environmental factors affect species distribution, and identify the shifts in the distribution of this species in various climate change scenarios. Our findings show habitat in provinces in the southern Qinling and Huai river basins have high environmental suitability. Temperature seasonality, annual precipitation, annual mean temperature, and warmest quarter precipitation were the most important factors affecting its distribution. Under a climate change scenario, the appropriate habitat range showed northeastward expansion geographically. The results in the present work can lay the foundation for the cultivation and conservation of Z.

Zelkova Serrata 'Green Vase'
Fact Sheet ST-678 October 1994 Zelkova serrata ‘Green Vase’ ‘Green Vase’ Japanese Zelkova1 Edward F. Gilman and Dennis G. Watson2 INTRODUCTION ‘Green Vase’ somewhat resembles the vase shape of American Elms, is more upright in habit and tolerant of pollution, makes a great city street tree and produces a taller and narrower tree than ‘Village Green’ Zelkova (Fig. 1). Zelkova is often listed as a replacement for American Elm since it has roughly the same vase shape and grows 70 to 80 feet tall with a 50 to 60-foot spread. But no tree will truly match the grace and elegance of the American Elm. Zelkova is massive, with the trunk capable of growing to four feet or more in diameter. It has a moderate growth rate and likes a sunny exposure. Branches are more numerous and smaller in diameter than American Elm. Major branches grow very upright and provide easy clearance for tall vehicles below making it quite suitable as a street tree. Leaves are 1.5 to 4 inches long, turning a brilliant burnt umber in the fall. GENERAL INFORMATION Scientific name: Zelkova serrata ‘Green Vase’ Figure 1. Young ‘Green Vase’ Japanese Zelkova.

Taxonomic Relationships and Population Differentiation of the South-Western Eurasian Zelkova Species Inferred in Leaf Morphology
2021, vol. 85, 60–77 https://doi.org/10.12657/denbio.085.007 Anna K. Jasińska, Beata Rucińska, Gregor Kozlowski, Laurence Fazan, Giuseppe Garfì, Salvatore Pasta, Sébastien Bétrisey, Emanuel Gerber, Krystyna Boratyńska, Adam Boratyński* Taxonomic relationships and population differentiation of the south-western Eurasian Zelkova species inferred in leaf morphology Received: 16 December 2020; Accepted: 19 February 2021 Abstract: The relict tree species Zelkova abelicea and Z. sicula (Ulmaceae) occur in Crete and Sicily, respec- tively. Zelkova abelicea grows in approximately 40 localities in the mountains of Crete, while Z. sicula has been found in only two stands in Sicily. We compared 25 morphological characters of the leaves of both species and used statistical methods (Tuk- ey’s test, discrimination analysis, principal component analysis, agglomeration) to reveal the differences between these two species, their relation to Z. carpinifolia (the third Zelkova south-west Eurasian species), and between the leaves from different shoot types. Our study represents the first comparative biometric analysis of the three Zelkova species localized in the western edge of the current geographic range of the genus. We found that the species differed from each other both, in terms of leaf form characters and level of leaf variation. Zelkova carpinifolia was clearly differ- ent from Z. abelicea, while the two populations of Z. sicula, SIB and SIA, were more similar to Z. carpinifolia and Z. abelicea, respectively. The latter finding supports the results of recent molecular studies suggesting the hybrid origin of Z. sicula. Zelkova abelicea, Z. sicula and Z. carpinifolia differ each other in the leaf characteristics and level of phenotypic variation.

Invasive Plant List
NON-NATIVE INVASIVE PLANTS OF ARLINGTON COUNTY, VIRGINIA While up to 40% of the plants found in a typical urban environment are non-native species, a relatively small number of these “alien” plants are known to represent an ecological threat to the natural environment (parks, woodlands, and backyards). Known as “invasive species”, these non-natives will spread from urban plantings into natural areas, eliminate native species, alter natural plant communities, and degrade the environment. The following plants have been documented as invasive species in Arlington. Known invasive plant species should not be planted as part of any Arlington County sponsored project. This list will be periodically reviewed by the Invasive Plant Coordinator (DPR) and updated by Version (date).

Zelkova Serrata.Cdr
Japanese Gray-Bark Elm - Zelkova serrata General information: Zelkova is often listed as a replacement for American Elm since it has roughly the same vase shape and grows 90 to 100 feet tall with a 60 to 80 foot spread. Zelkova is massive, with the trunk capable of growing to four feet or more in diameter. It has a moderate growth rate and likes a sunny exposure. Branches are more numerous and smaller in diameter than American Elm. Leaves are 1.5 to 4 inches long, turning a brilliant yellow, orange, or burnt umber in the fall. This elm is a native of Japan and China and is related to the Ulmus genus, which is the genus of the European and American elms. It is deciduous with small ovate, serrated, pointed leaves and smooth gray bark. It is a vigorous grower and is most often used for broom and group plantings. Root-over- rock plantings are also common. The gray-bark elm is considered by some to be the classic broom style tree. Family: Ulmaceae Lighting: Full sun to part shade. During summer in southern part of USA, do not expose the tree to direct sun during the heat of the day. Temperature: Zones 5 through 8. Make sure the tree has good winter protection. Watering: Allow the soil to dry slightly between waterings. Spray the foliage with water daily during the summer. Feeding: Feed every 20-30 days with a slow-acting fertilizer during spring and again from late summer through mid-autumn. If you prefer to use chemical fertilizers, feed every other week using a half-strength solution of a balanced fertilizer such as Peter's 20-20-20.
