Japanese Maples – Acer Spp
Japanese Maples – Acer spp. Known for their astounding variety in color, texture and habit, Japanese Maples are easygoing and adaptable and belong in every garden. If you already have one, think about adding another! for every site, a japanese maple! • Botanists count twenty-three species to include under the common heading of Japanese Maple. The largest group is Acer palmatum and its cultivars, followed by Acer japonicum. The numerous cultivars of Acer palmatum are further divided into seven groups which are mostly defined by leaf-shape. • In addition to variation in leaf-shape, Japanese Maples come in an array of sizes, growth habits, color ranges, and full sun to part shade preference. They add structure, contrast, texture, and beauty to any garden. • Carefully evaluate your chosen planting spot: Japanese maples require a slightly acid, sandy loam, with medium moisture and good drainage. Regular leafed varieties take full sun better than laceleaf types, but all Japanese Maples will be happy with at least some afternoon shade, since St. Louis summer sun is hot, strong and humid. • Remember that plants grow outwards as well as upwards and site appropriately. Take into account proximity to any buildings and any overhead limits. Some pruning is possible but should not be a necessary task. • The main requirement of a Japanese Maple is a uniform supply of water. They are not happy with very wet periods followed by long, dry periods or vice versa. Most will need supplemental water in the St. Louis summers. Japanese Maples in planters have this same need for consistency – be careful that they do not become waterlogged! prepare your site, plant your tree • Japanese Maples are easy to plant. -

Non-Native Trees and Large Shrubs for the Washington, D.C. Area
Green Spring Gardens 4603 Green Spring Rd ● Alexandria ● VA 22312 Phone: 703-642-5173 ● TTY: 703-803-3354 www.fairfaxcounty.gov/parks/greenspring NON - NATIVE TREES AND LARGE SHRUBS FOR THE WASHINGTON, D.C. AREA Non-native trees are some of the most beloved plants in the landscape due to their beauty. In addition, these trees are grown for the shade, screening, structure, and landscape benefits they provide. Deciduous trees, whose leaves die and fall off in the autumn, are valuable additions to landscapes because of their changing interest throughout the year. Evergreen trees are valued for their year-round beauty and shelter for wildlife. Evergreens are often grouped into two categories, broadleaf evergreens and conifers. Broadleaf evergreens have broad, flat leaves. They also may have showy flowers, such as Camellia oleifera (a large shrub), or colorful fruits, such as Nellie R. Stevens holly. Coniferous evergreens either have needle-like foliage, such as the lacebark pine, or scale-like foliage, such as the green giant arborvitae. Conifers do not have true flowers or fruits but bear cones. Though most conifers are evergreen, exceptions exist. Dawn redwood, for example, loses its needles each fall. The following are useful definitions: Cultivar (cv.) - a cultivated variety designated by single quotes, such as ‘Autumn Gold’. A variety (var.) or subspecies (subsp.), in contrast, is found in nature and is a subdivision of a species (a variety of Cedar of Lebanon is listed). Full Shade - the amount of light under a dense deciduous tree canopy or beneath evergreens. Full Sun - at least 6 hours of sun daily. -

The Gnome Desktop Comes to Hp-Ux
GNOME on HP-UX Stormy Peters Hewlett-Packard Company 970-898-7277 [email protected] THE GNOME DESKTOP COMES TO HP-UX by Stormy Peters, Jim Leth, and Aaron Weber At the Linux World Expo in San Jose last August, a consortium of companies, including Hewlett-Packard, inaugurated the GNOME Foundation to further the goals of the GNOME project. An organization of open-source software developers, the GNOME project is the major force behind the GNOME desktop: a powerful, open-source desktop environment with an intuitive user interface, a component-based architecture, and an outstanding set of applications for both developers and users. The GNOME Foundation will provide resources to coordinate releases, determine future project directions, and promote GNOME through communication and press releases. At the same conference in San Jose, Hewlett-Packard also announced that GNOME would become the default HP-UX desktop environment. This will enhance the user experience on HP-UX, providing a full feature set and access to new applications, and also will allow commonality of desktops across different vendors' implementations of UNIX and Linux. HP will provide transition tools for migrating users from CDE to GNOME, and support for GNOME will be available from HP. Those users who wish to remain with CDE will continue to be supported. Hewlett-Packard, working with Ximian, Inc. (formerly known as Helix Code), will be providing the GNOME desktop on HP-UX. Ximian is an open-source desktop company that currently employs many of the original and current developers of GNOME, including Miguel de Icaza. They have developed and contributed applications such as Evolution and Red Carpet to GNOME. -
For Japananus Hyalinus
Rapid Pest Risk Analysis (PRA) for Japananus hyalinus STAGE 1: INITIATION 1. What is the name of the pest? Japananus hyalinus (Osborn) Hemiptera Cicadellidae Japanese maple leafhopper Synonyms: Japananus meridionalis Bonfils Platymetopius cinctus Matsumura Platymetopius hyalinus Osborn 2. What initiated this rapid PRA? In 1999 two leafhoppers identified as J. hyalinus were intercepted on Acer palmatum 'Katsura' imported from South Korea. An entry for this species was included on the UK Plant Health Pest Risk Register in 2013 and identified as a priority to update a previous PRA written in 1999 (Fera 2013), in particular to assess its potential establishment given the spread of J. hyalinus across Europe (Mifsud et al. 2010). 3. What is the PRA area? The PRA area is the United Kingdom of Great Britain and Northern Ireland. STAGE 2: RISK ASSESSMENT 4. What is the pest’s status in the EC Plant Health Directive (Council Directive 2000/29/EC1) and in the lists of EPPO2? The pest is not listed in the EC Plant Health Directive and is not recommended for regulation as a quarantine pest by EPPO, nor is it on the EPPO Alert List. 5. What is the pest’s current geographical distribution? J. hyalinus was first identified from the USA, but it is widely believed to originate from eastern Asia, though some authors dispute this due to the main host plant in Europe being the native Acer campestre, rather than ornamentally grown Asian species (Nickel and Remane 2002). It was first introduced into Europe in Austria in 1961, but its range has expanded considerably in recent years (Mifsud et al. -

We investigated whether a root-feeding moth found closely associated with oxeye daisy in Europe could be used as a biological control agent for the plant when weedy. We found that the moth could develop on 11 out of 74 plant species that we tested in laboratory conditions when it was given no choice of plants.

Identification of 16Srix-C Phytoplasmas in Argyranthemum
Phytopathologia Mediterranea (2015) 54, 1, 21−27 DOI: 10.14601/Phytopathol_Mediterr-14431 RESEARCH PAPER Identification of 16SrIX-C phytoplasmas in Argyranthemum frutescens in Italy LUCA FERRETTI, ELISA COSTANTINI and GRAZIELLA PASQUINI Agricultural Research Council, Plant Pathology Research Centre (CRA-PAV), Via C. G. Bertero 22, 00156 Roma, Italy Summary. Phytoplasmas are cell wall-less microorganisms associated with plant diseases worldwide. Many im- portant food, vegetable and fruits crops as well as ornamental plants can be severely affected by these pathogens, with significant economic impacts. Phytoplasma diseases of ornamentals have been described worldwide in a wide range of plant genera, and 11 different 16Sr groups have been identified. In Italy, many ornamental plant species belonging to several botanical families have been found to be infected by phytoplasmas, classified into the ribosomal groups 16SrI, 16SrII, 16SrV and 16SrXII. During a survey carried out in commercial gardens in Rome, some marguerite daisy (Argyranthemum frutescens) plants showing symptoms of phytoplasma-like disease, were collected and submitted to molecular analyses. Cloning and sequencing of the portion of the 16S rRNA gene fol- lowed by BLAST analysis, real and virtual restriction fragment length polymorphism anlaysis with AluI and RsaI, allowed assignment of the detected phytoplasma to the 16SrIX-C group (Picris echioides yellows, PEY).

The review also highlighted synonymy with Rarosiella cocosae found on coconut in the Philippines.
