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 -
"National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary."
Intro 1996 National List of Vascular Plant Species That Occur in Wetlands The Fish and Wildlife Service has prepared a National List of Vascular Plant Species That Occur in Wetlands: 1996 National Summary (1996 National List). The 1996 National List is a draft revision of the National List of Plant Species That Occur in Wetlands: 1988 National Summary (Reed 1988) (1988 National List). The 1996 National List is provided to encourage additional public review and comments on the draft regional wetland indicator assignments. The 1996 National List reflects a significant amount of new information that has become available since 1988 on the wetland affinity of vascular plants. This new information has resulted from the extensive use of the 1988 National List in the field by individuals involved in wetland and other resource inventories, wetland identification and delineation, and wetland research. Interim Regional Interagency Review Panel (Regional Panel) changes in indicator status as well as additions and deletions to the 1988 National List were documented in Regional supplements. The National List was originally developed as an appendix to the Classification of Wetlands and Deepwater Habitats of the United States (Cowardin et al.1979) to aid in the consistent application of this classification system for wetlands in the field.. The 1996 National List also was developed to aid in determining the presence of hydrophytic vegetation in the Clean Water Act Section 404 wetland regulatory program and in the implementation of the swampbuster provisions of the Food Security Act. While not required by law or regulation, the Fish and Wildlife Service is making the 1996 National List available for review and comment. -
Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE
Guide to the Flora of the Carolinas, Virginia, and Georgia, Working Draft of 17 March 2004 -- LILIACEAE LILIACEAE de Jussieu 1789 (Lily Family) (also see AGAVACEAE, ALLIACEAE, ALSTROEMERIACEAE, AMARYLLIDACEAE, ASPARAGACEAE, COLCHICACEAE, HEMEROCALLIDACEAE, HOSTACEAE, HYACINTHACEAE, HYPOXIDACEAE, MELANTHIACEAE, NARTHECIACEAE, RUSCACEAE, SMILACACEAE, THEMIDACEAE, TOFIELDIACEAE) As here interpreted narrowly, the Liliaceae constitutes about 11 genera and 550 species, of the Northern Hemisphere. There has been much recent investigation and re-interpretation of evidence regarding the upper-level taxonomy of the Liliales, with strong suggestions that the broad Liliaceae recognized by Cronquist (1981) is artificial and polyphyletic. Cronquist (1993) himself concurs, at least to a degree: "we still await a comprehensive reorganization of the lilies into several families more comparable to other recognized families of angiosperms." Dahlgren & Clifford (1982) and Dahlgren, Clifford, & Yeo (1985) synthesized an early phase in the modern revolution of monocot taxonomy. Since then, additional research, especially molecular (Duvall et al. 1993, Chase et al. 1993, Bogler & Simpson 1995, and many others), has strongly validated the general lines (and many details) of Dahlgren's arrangement. The most recent synthesis (Kubitzki 1998a) is followed as the basis for familial and generic taxonomy of the lilies and their relatives (see summary below). References: Angiosperm Phylogeny Group (1998, 2003); Tamura in Kubitzki (1998a). Our “liliaceous” genera (members of orders placed in the Lilianae) are therefore divided as shown below, largely following Kubitzki (1998a) and some more recent molecular analyses. ALISMATALES TOFIELDIACEAE: Pleea, Tofieldia. LILIALES ALSTROEMERIACEAE: Alstroemeria COLCHICACEAE: Colchicum, Uvularia. LILIACEAE: Clintonia, Erythronium, Lilium, Medeola, Prosartes, Streptopus, Tricyrtis, Tulipa. MELANTHIACEAE: Amianthium, Anticlea, Chamaelirium, Helonias, Melanthium, Schoenocaulon, Stenanthium, Veratrum, Toxicoscordion, Trillium, Xerophyllum, Zigadenus. -

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.

Picea Omorika Cultivation and Uses
Picea omorika From Wikipedia, the free encyclopedia Kingdom: Plantae Division: Pinophyta Picea omorika ( Serbian Spruce ) is a rare, local Class: Pinopsida spruce, endemic to the Drina River valley in western Serbia and eastern Bosnia and Herzegovina Order: Pinales near Višegrad. It was originally discovered near the Family: Pinaceae village of Zaovine on the Tara Mountain in 1875, č ć Genus: Picea and named by the Serbian botanist Josif Pan i ; the epithet omorika is simply the Serbian word for P. omorika Species: "spruce"; hence, the scientific name means"Spruce- spruce". It is a medium-sized evergreen tree growing to 20–35 m tall, exceptionally to 40 m tall, and with a trunk diameter of up to 1 m. The shoots are buff-brown, and densely pubescent (hairy). The leaves are needle-like, 10–20 mm long, flattened in cross-section, and dark blue-green above, and blue-white below. The cones are 4–7 cm long, fusiform (spindle-shaped, broadest in the middle), dark purple (almost black) when young, maturing dark brown 5–7 months after pollination, and have stiff scales. Cultivation and uses Outside of its native range, Serbian Spruce is of major importance in horticulture as an ornamental tree in large gardens, valued in northern Europe and North America for its very attractive crown form and ability to grow on a wide range of soils, including alkaline, clay, acid and sandy soil, although it prefers moist, drained loam. It is also grown to a small extent in forestry for christmas trees, timber and paper production, particularly in northern Europe, though its slow growth makes it less important than Sitka Spruce or Norway Spruce. -

Pinus Parviflora Japanese White Pine1 Edward F
Fact Sheet ST-470 October 1994 Pinus parviflora Japanese White Pine1 Edward F. Gilman and Dennis G. Watson2 INTRODUCTION Japanese White Pine creates a striking landscape element wherever it is used (Fig. 1). Often seen as a dense, conical form when young, Japanese White Pine develops into a 25 to 50-foot-tall, graceful, irregularly- shaped tree, with an equal or greater spread, and a broad, flattened canopy. The 1 to 2.5-inch-long needles are stiff and twisted, forming blue/green tufts of foliage at branch tips, and creating an overall fine texture to the tree’s silhouette. The brownish-red cones are one to four inches long and persist on the tree for six to seven years. GENERAL INFORMATION Scientific name: Pinus parviflora Figure 1. Young Japanese White Pine. Pronunciation: PIE-nus par-vih-FLOR-uh Common name(s): Japanese White Pine Texture: fine Family: Pinaceae USDA hardiness zones: 4B through 7A (Fig. 2) Foliage Origin: not native to North America Uses: Bonsai; screen; specimen; no proven urban Leaf arrangement: alternate; spiral (Fig. 3) tolerance Leaf type: simple Availability: somewhat available, may have to go out Leaf margin: entire of the region to find the tree Leaf shape: needle-like (filiform) Leaf venation: parallel DESCRIPTION Leaf type and persistence: evergreen; fragrant; needle leaf evergreen Height: 25 to 50 feet Leaf blade length: 2 to 4 inches; less than 2 inches Spread: 25 to 50 feet Leaf color: blue or blue-green; green Crown uniformity: irregular outline or silhouette Fall color: no fall color change Crown shape: spreading; pyramidal Fall characteristic: not showy Crown density: dense Growth rate: slow 1. -
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). -
