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 -

Plant Materials Tech Note
United States Department of Agriculture NATURAL RESOURCES CONSERVATION SERVICE Plant Materials Plant Materials Technical Note No. MT-33 September 1999 PLANT MATERIALS TECH NOTE DESCRIPTION, PROPAGATION, AND USE OF SILVERBERRY Elaeagnus commutata. Introduction: Silverberry Elaeagnus commutata Bernh. ex. Rydb is a native shrub with potential use in streambank stabilization, wildlife habitat, windbreaks, and naturalistic landscaping projects. The purpose of this bulletin is to transfer information on the identification, culture, and proper use of this species. FIGURE 1 FRUIT STEM FOLIAGE I. DESCRIPTION Silverberry is a multi-stemmed, deciduous shrub ranging from 1.5 to 3.6 m (5 to 12 ft.) tall. In Montana, heights of 1.5 to 2.4 m (5 to 8 ft.) are most common. It has an erect, upright habit with slender and sometimes twisted branches. The new stems are initially a light to medium brown color, the bark becoming dark gray, but remaining smooth, with age. The leaves are deciduous, alternate, 38 to 89 mm (1.5 to 3.5 in.) long and 19 to 38 mm (0.75 to 1.5 in.) wide (see Figure 1). The leaf shape is described as oval to narrowly ovate with an entire leaf margin. Both the upper and lower leaf surfaces are covered with silvery white scales, the bottom sometimes with brown spots. The highly fragrant, yellow flowers are trumpet-shaped (tubular), approximately 13 mm (0.5 in.) in length, and borne in the leaf axils in large numbers in May or June. The fruit is a silvery-colored, 7.6 mm (0.3 in.) long, egg-shaped drupe that ripens in September to October. -
Rhodotypos Scandens Common Name: Black Jetbead Family Name
Plant Profiles: HORT 2241 Landscape Plants I Botanical Name: Rhodotypos scandens Common Name: black jetbead Family Name: Rosaceae –rose family General Description: Rhodotypos scandens is a tough, adaptable flowering shrub. It has white flowers in late spring, handsome leaves during the summer and fall, and interesting small black fruits that hold on during the winter. It does well in sun or dense shade and is tolerant of a wide variety of landscape conditions. Rhodotypos scandens was introduced from Asia for use as an ornamental plant but has become an invasive species in eastern United States. Though not a widespread problem in this area, it has been documented in natural areas in DuPage, Cook and a few other areas on the Chicago area. Zone: 4-8 Resources Consulted: Dirr, Michael A.

Plants were monitored for five consecutive years in six study plots in Oulanka, northern Finland. Sex ratio, spatial distribution of sexes, flowering frequency, number of floral shoots and the number and weight of inflorescences were recorded. In addition, intensity of mycorrhizal fungi in the roots was assessed. Both sexes flowered each year with a similar frequency, but the overall genet sex ratio was strongly female-biased. The bivariate Ripley’s analysis of the sex distribution showed that within most plots sexes were randomly distributed except for one plot. Sexual dimorphism was expressed as larger floral and inflorescence production and heavier inflorescences in males. In addition, the roots of both sexes were colonised to a similar extent by arbuscular mycorrhizal fungi. The female sex-biased flowering ratios reported are not consistent among years and cannot be explained in terms of spatial segregation of the sexes or sex lability. -
Literature Cited
Literature Cited Robert W. Kiger, Editor This is a consolidated list of all works cited in volumes 19, 20, and 21, whether as selected references, in text, or in nomenclatural contexts. In citations of articles, both here and in the taxonomic treatments, and also in nomenclatural citations, the titles of serials are rendered in the forms recommended in G. D. R. Bridson and E. R. Smith (1991). When those forms are abbre- viated, as most are, cross references to the corresponding full serial titles are interpolated here alphabetically by abbreviated form. In nomenclatural citations (only), book titles are rendered in the abbreviated forms recommended in F. A. Stafleu and R. S. Cowan (1976–1988) and F. A. Stafleu and E. A. Mennega (1992+). Here, those abbreviated forms are indicated parenthetically following the full citations of the corresponding works, and cross references to the full citations are interpolated in the list alphabetically by abbreviated form. Two or more works published in the same year by the same author or group of coauthors will be distinguished uniquely and consistently throughout all volumes of Flora of North America by lower-case letters (b, c, d, ...) suffixed to the date for the second and subsequent works in the set. The suffixes are assigned in order of editorial encounter and do not reflect chronological sequence of publication. The first work by any particular author or group from any given year carries the implicit date suffix “a”; thus, the sequence of explicit suffixes begins with “b”. Works missing from any suffixed sequence here are ones cited elsewhere in the Flora that are not pertinent in these volumes. -

Morphology and Morphogenesis of the Seed Cones of the Cupressaceae - Part II Cupressoideae
1 2 Bull. CCP 4 (2): 51-78. (10.2015) A. Jagel & V.M. Dörken Morphology and morphogenesis of the seed cones of the Cupressaceae - part II Cupressoideae Summary The cone morphology of the Cupressoideae genera Calocedrus, Thuja, Thujopsis, Chamaecyparis, Fokienia, Platycladus, Microbiota, Tetraclinis, Cupressus and Juniperus are presented in young stages, at pollination time as well as at maturity. Typical cone diagrams were drawn for each genus. In contrast to the taxodiaceous Cupressaceae, in Cupressoideae outgrowths of the seed-scale do not exist; the seed scale is completely reduced to the ovules, inserted in the axil of the cone scale. The cone scale represents the bract scale and is not a bract- /seed scale complex as is often postulated. Especially within the strongly derived groups of the Cupressoideae an increased number of ovules and the appearance of more than one row of ovules occurs. The ovules in a row develop centripetally. Each row represents one of ascending accessory shoots. Within a cone the ovules develop from proximal to distal. Within the Cupressoideae a distinct tendency can be observed shifting the fertile zone in distal parts of the cone by reducing sterile elements. In some of the most derived taxa the ovules are no longer (only) inserted axillary, but (additionally) terminal at the end of the cone axis or they alternate to the terminal cone scales (Microbiota, Tetraclinis, Juniperus). Such non-axillary ovules could be regarded as derived from axillary ones (Microbiota) or they develop directly from the apical meristem and represent elements of a terminal short-shoot (Tetraclinis, Juniperus). -

Grows vertically with a straight main trunk. The winter buds are a remarkable brownish-red colour and glossy. In the spring the young leaves emerge almost white. Once they are fully grown only the underside remains a remarkable light grey. The leaves are rough and slightly lobed. No other ornamental apple tree has such exceptional autumnal colours as this. With its many shades, from purple and copper through orange to yellow, the tree is a real eye-catcher in the autumn. The (fragrant) flowers and the fruits are much less spectacular than those of the other ornamental apple trees. -
