Department of Planning and Zoning
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 -
P L a N T L I S T Water-Wise Trees and Shrubs for the High Plains
P L A N T L I S T Water-Wise Trees and Shrubs for the High Plains By Steve Scott, Cheyenne Botanic Gardens Horticulturist 03302004 © Cheyenne Botanic Gardens 2003 710 S. Lions Park Dr., Cheyenne WY, 82001 www.botanic.org The following is a list of suitable water-wise trees and shrubs that are suitable for water- wise landscaping also known as xeriscapes. Many of these plants may suffer if they are placed in areas receiving more than ¾ of an inch of water per week in summer. Even drought tolerant trees and shrubs are doomed to failure if grasses or weeds are growing directly under and around the plant, especially during the first few years. It is best to practice tillage, hoeing, hand pulling or an approved herbicide to kill all competing vegetation for the first five to eight years of establishment. Avoid sweetening the planting hole with manure or compost. If the soil is needs improvement, improve the whole area, not just the planting hole. Trees and shrubs generally do best well with no amendments. Many of the plants listed here are not available in department type stores. Your best bets for finding these plants will be in local nurseries- shop your hometown first! Take this list with you. Encourage nurseries and landscapers to carry these plants! For more information on any of these plants please contact the Cheyenne Botanic Gardens (307-637-6458), the Cheyenne Forestry Department (307-637-6428) or your favorite local nursery.

Climate Ready Trees for Central Valley Communities
The goal of this study is to evaluate the survival and growth of seldom used but promising trees in the Central Valley. We can create more resilient Climate Ready Trees for urban forests by shifting the palate of trees planted to those proven to Central Valley Communities perform best when exposed to climate stressors such as heat, drought, high winds, pests, disease and soil salinity. 1. Mulga (Acacia aneura) Mulga is native to arid Western Australia and tolerates hot and dry conditions. It can grow in sandy, loam, or clay soil types. This versatile and hardy tree produces ascending thornless branches and grows 15 to 20 feet in height. The evergreen foliage is gray-green and the tree has yellow flowers in the spring. Maintain leader to avoid suckering. 2. Netleaf Hackberry (Celtis reticulata) The Netleaf Hackberry is native to riparian areas in the Southwest. A deciduous tree, it reaches heights of 25 to 35 feet with a spreading or weeping canopy. The ovate leaves are medium green and turn yellow in the fall. The flowers mature into red drupes that attract birds. The Netleaf Hackberry is drought tolerant and able to thrive in variety of soil types. 3. Desert Willow (Chilopsis linearis ‘Bubba’) The Desert Willow is a small flowering desert tree native to California and the Southwest. The cultivar Bubba can reach 25 to 30 feet with a spread of 20 to 25 feet. It has profuse, long- lasting blooms. The showy flowers are pink and white. Leaves are linear blue green and turn golden in the fall. -
Propagation of Colorado Natives at Little Valley©
224 Combined Proceedings International Plant Propagators’ Society, Volume 58, 2008 Propagation of Colorado Natives at Little Valley © Brian Core Little Valley Wholesale Nursery, 13022 E. 136th Ave., Brighton, Colorado 80601 U.S.A. Email: [email protected] INTRODUCTION Little Valley Wholesale Nursery was established in 1979 with 15 acres of field and container stock and a staff of four people. Over the years, it has expanded to en- compass 141 acres and a peak-season staff of more than 150 people. The plant palette now includes more than 500 taxa of perennials, 275 taxa of shrubs, and over 130 taxa of trees. The area served by Little Valley’s distribution system includes Wyoming, Colorado, New Mexico, and Arizona. Little Valley’s motto “The Rocky Mountain Standard” expresses the commitment to be the best wholesale plant dis- tributor in the western region. Native plants have been an important part of Little Valley’s plant mix for many years. Native plants are ideal for low-input sustainable landscapes. The Denver Metro area receives 8–15 inches of rain per year; in contrast, many eastern cities receive 50 or even 60 inches of annual precipitation. Colorado has a rapidly expanding population that threatens to deplete the water supply within a few decades. Many native plants require no supplemental water when established in the landscape; water that is not wasted on bluegrass lawns is water that can be used for human consumption. Native plants also require less frequent fertilizer and pesticide appli- cations; overuse of fertilizer and pesticide can lead to contamination of groundwater supplies with carcinogens. -
Northstar Fire Department, Fire Resistant Landscaping Plant List
Northstar Fire Department, Fire Resistant Landscaping Plant List Many common plants naturally resist fire and can even slow its spread. In general, irrigated and well maintained leafy plants burn slowly. By replacing highly flammable vegetation with these fire resistant recommended species, you can significantly improve the statistical survivability of your home when a wildfire threatens. Courtesy of the “Villager Nursery” in Truckee, this list of fire resistive plants should be considered when enhancing or adding landscape. Here are some other key components to remember when selecting appropriate fire resistant landscaping plants. Choose plants that don’t produce much litter such as dead branches and twigs Plants that produce oils, resins or waxes should be avoided When planting from the approved list, appropriately space plants to prevent fire spread Never plant under conifer trees, this can create a ladder effect which allows smaller ground fires the ability to transfer into larger trees creating crown fires To help ensure their fire resistance, plants must be maintained, watered, and pruned. Routine care will provide you with an attractive defensible space landscape and help ensure the survival of your property in the event of a wildfire. Northstar Fire Department enforces both State and District fire codes that may directly affect your landscape. Northstar Fire Department recommends that prior to changing your landscape you consult with us in order to make sure your property will be compliant with applicable fire codes.

ECOLOGICAL and ECONOMIC IMPORTANCE of STUDYING PROPAGATION TECHNIQUES of COMMON HAWTHORN Crataegus Monogyna Jacq. G
СИБИРСКИЙ ЛЕСНОЙ ЖУРНАЛ. 2019. № 4. С. 63–67 UDC 581.16/581.6/581.9:634.17 ECOLOGICAL AND ECONOMIC IMPORTANCE OF STUDYING PROPAGATION TECHNIQUES OF COMMON HAWTHORN Crataegus monogyna Jacq. G. Özyurt, Z. Yücesan, N. Ak, E. Oktan, A. Ö. Üçler Karadeniz Technical University Trabzon, 61080 Turkey E-mail: [email protected], [email protected], [email protected], [email protected], [email protected] Received 11.04.2019 Climate change as a fact of global warming requires the development of different perspectives on the planning and implementation of sustainable forestry techniques. Increasing temperatures cause drought on a global basis. In connection with, this using drought tolerant species in afforestation work is of great importance. In recent years Crataegus L. species (hawthorn) are also involved in afforestation. One of these species, C. monogyna, is characterized by drought tolerance. Furthermore, C. monogyna is the most important nonwood forest product species of Turkey. Hawthorn is widely used in medicine (treatment of coronary heart diseases), and cosmetics industry, agriculture and animal husbandry and human nutrition. On the other hand, it is used in erosion control, afforestation, industrial energy resources and for landscaping. Economic and ecological contribution of hawthorn to the national economy is quite high. Therefore, determination of suitable generative and vegetative reproduction techniques and vast production of seedlings of hawthorn species are extremely important. The characteristics of generative and vegetative propagation of Crataegus are discussed. For generative propagation of hawthorn species, the most effective and suitable procedure is treatment of seeds in ash solution. For vegetative propagation in culture in vitro the growth induced by BA (benzyladenine) and IBA (indole butyric acid) hormones increases the rate of callus formation and rooting. -
Alnus Glutinosa Common Name
Plant Profiles: HORT 2242 Landscape Plants II Botanical Name: Alnus glutinosa Common Name: European alder, common alder, black alder Family Name: Betulaceae - birch family General Description: Alnus glutinosa is an intermediate size tree that can be grown single stem or clump. It has been a popular plant in the landscape due to its size, shape, winter texture and ability to grow in diverse landscape settings. European black alder is especially useful for wet sites and poor infertile sites as it has the ability to fix nitrogen in nodules on its root system. However, it is a non-native tree that has escaped cultivation and can now be found along rivers and other natural habitats in the Chicago area. According to The Morton Arboretum, this plant is invasive and should not be planted. Zone: 3-7 Resources Consulted: "Black alder." Trees & Plants. Morton Arboretum, 2013. Web. 26 Feb. 2014.
