    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

This research reflects the data available at the time this evaluation was conducted. Summary Euonymus alatus is naturalized across much of Eastern North America. It is a 1 to 4 meter tall shrub which an produce thickets in forest understory, displacing native vegetation. Seed production is prolific and dispersed by birds. General Information Status: Submitted Screener: Kim Taylor Evaluation Date: September 21, 2017 Plant Information Plant: Euonymus alatus If the plant is a cultivar, how does its behavior differs from its parent's?

  • Studies of Fruit and Seed Characters of Selected Euonymus Species Bernd Schulz, Translated by Wolfgang Bopp
    Studies of fruit and seed characters of selected Euonymus species Bernd Schulz, translated by Wolfgang Bopp Summary Euonymus species are particularly prized for their decorative fruits. This work describes and illustrates (in water colour), the fruits and seeds of 30 commonly cultivated species found in Central European plant collections. The text discusses the criteria for species differentiation. As well as the shape of the fruits and seeds, seed colouration is described and compared to several published accounts in an attempt to correct previous misconceptions. This paper was originally published in German in 2006 (Schulz, 2006a). This translation contains some minor additions and adjustments to the original text and has been translated to the best of our ability, albeit not being a 100% accurate translation. 1 Introduction The German common name of Euonymus europaeus, is “Pfaffenhütchen” which translates as priest’s hat or mitre, in reference to its shape. In past centuries, the wearing of such a hat was a status symbol, showing the belonging to a professional group. Priests in Germany have, since the sixteenth century, been wearing the so-called biretta1,”a stiff and square-shaped head covering as worn by priests, also found in a wider and bigger version“ (Loschek 1993). In Germany today certain clerics wear a very similar head covering, closely resembling the shape of Euonymus europaeus fruits. While I never intended to get as closely involved with this genus, the very attractive nature of the fruits and seeds captivated me, and led me to produce this work. Prior to turning to the fruits of woody broadleaves, I primarily studied the winter buds and twigs of deciduous trees and shrubs (Schulz 1999, 2004, 2006b), a subject which was then little published, apart from the works by Schneider (1903) and Trelease (1931).

    Winged Euonymus or Invasive Plant Information Sheet Burning Bush Euonymus alatus Staff-tree Family (Celastraceae) Description: Winged Euonymus is a deciduous shrub that averages 6 to 9 feet in height but is capable of reaching 15 feet. It has opposite, simple, elliptical toothed leaves which turn bright scarlet in autumn. Among its distinctive features are the prominently corky-winged green and brown twigs. The fruit is a cluster of pods, usually four, which are quite showy. These purple fruits split open when ripe revealing the bright red inner parts. Origin: Native to eastern Asia, surface.

  • Euonymus Alatus (Winged Burning Bush)
    Green Gone Bad Featured Ornamental Plant: Euonymus alatus (Winged Burning Bush) Some exotic ornamental plants behave badly when they escape from the place they are planted. Infestations of these plants have negative impacts on nature. One of these plants is Euonymus alatus; common name: Winged Burning Bush. EUONYMUS ALATUS is an ornamental shrub often planted for the attractive fall foliage. It is called Winged Burning Bush because of the 4 ridges on the stems and the bright red fall leaf color. This shrub was introduced from northeast Asia in the 1860’s. J. Miller, Bugwood Euonymus alatus is a deciduous multi-stemmed shrub that grows from 5-10 feet tall and sometimes up to 20 feet. Leaves are opposite, elliptic, and finely toothed; 1-4 inches long, dark green before turning red in the fall. Small yellowish-green flowers bloom in pairs during late spring. The fruit is a reddish dangling capsule turning purple when ripe. The problem with Euonymus alatus is that it can escape from planted landscapes into natural areas. It spreads through J. Miller, Bugwood vegetative growth by root suckering. Seeds can also be spread by birds. Once established in mature forests, this vegetative growth forms dense thickets that can inhibit native plant growth and germination through shading and competition for nutrients and water in the soil. This results in reduction of plant biodiversity J. Miller, Bugwood and overall quality of natural communities. Once native plant communities are altered, wildlife populations may suffer due to the change in habitat structure (needed for nesting and cover) and reduction in food resources (insect abundance often drops in infested areas).
