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 -
Foundation Arboretum Wespelaar Year Report 2019
Foundation Arboretum Wespelaar Year Report 2019 2019 started with an early spring: by mid-March the early magnolias were in full flower. Temperatures kept rising and the heat record was broken in July, making the summer of 2019 one to be recorded in history books. Luckily, small rain showers and increased irrigation capacities ensured that we lost very few plants. In March 2019, the construction of the Artois Pavilion started in the Artois Meadow, at the end of two important vistas. The design is inspired by the old pavilion along the canal in the Park of Wespelaar. In the new Arboretum de Marche, a total of 189 trees have been planted in the past two years. In collaboration with Natagora, five ponds were created and a 5ha plot was sown with wild seed to create a meadow of native grasses and flowers. The building permit for the visitors centre and technical facilities was obtained. 2019 was a very active year for both Arboretum Wespelaar and Arboretum de Marche, as is described in more detail in this Year Report. Arboretum Wespelaar – Year Report 2019 1 THE COLLECTIONS ‘Patty’ can be planted in the Arboretum in due time.

THE Magnoliaceae Liriodendron L. Magnolia L
THE Magnoliaceae Liriodendron L. Magnolia L. VEGETATIVE KEY TO SPECIES IN CULTIVATION Jan De Langhe (1 October 2014 - 28 May 2015) Vegetative identification key. Introduction: This key is based on vegetative characteristics, and therefore also of use when flowers and fruits are absent. - Use a 10× hand lens to evaluate stipular scars, buds and pubescence in general. - Look at the entire plant. Young specimens, shade, and strong shoots give an atypical view. - Beware of hybridisation, especially with plants raised from seed other than wild origin. Taxa treated in this key: see page 10. Questionable/frequently misapplied names: see page 10. Names referred to synonymy: see page 11.
