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. -

Fl. China 11: 516–553. 2008. 2. ACER Linnaeus, Sp. Pl. 2: 1054. 1753. 枫属 feng shu Trees or shrubs. Leaves mostly simple and palmately lobed or at least palmately veined, in a few species pinnately veined and entire or toothed, or pinnately or palmately 3–5-foliolate. Inflorescence corymbiform or umbelliform, sometimes racemose or large paniculate. Sepals (4 or)5, rarely 6. Petals (4 or)5, rarely 6, seldom absent. Stamens (4 or 5 or)8(or 10 or 12); filaments distinct. Carpels 2; ovules (1 or)2 per locule. Fruit a winged schizocarp, commonly a double samara, usually 1-seeded; embryo oily or starchy, radicle elongate, cotyledons 2, green, flat or plicate; endosperm absent. 2n = 26. About 129 species: widespread in both temperate and tropical regions of N Africa, Asia, Europe, and Central and North America; 99 species (61 endemic, three introduced) in China. Acer lanceolatum Molliard (Bull. Soc. Bot. France 50: 134. 1903), described from Guangxi, is an uncertain species and is therefore not accepted here. The type specimen, in Berlin (B), has been destroyed. Up to now, no additional specimens have been found that could help clarify the application of this name. Worldwide, Japanese maples are famous for their autumn color, and there are over 400 cultivars. Also, many Chinese maple trees have beautiful autumn colors and have been cultivated widely in Chinese gardens, such as Acer buergerianum, A. davidii, A. duplicatoserratum, A. griseum, A. pictum, A. tataricum subsp. ginnala, A. triflorum, A. truncatum, and A. wilsonii. In winter, the snake-bark maples (A. davidii and its relatives) and paper-bark maple (A. -

Commodity Risk Assessment of Acer Spp. Plants from New Zealand
SCIENTIFIC OPINION ADOPTED: 26 March 2020 doi: 10.2903/j.efsa.2020.6105 Commodity risk assessment of Acer spp. plants from New Zealand EFSA Panel on Plant Health (PLH), Claude Bragard, Katharina Dehnen-Schmutz, Francesco Di Serio, Marie-Agnes Jacques, Josep Anton Jaques Miret, Annemarie Fejer Justesen, Alan MacLeod, Christer Sven Magnusson, Panagiotis Milonas, Juan A Navas-Cortes, Stephen Parnell, Roel Potting, Philippe Lucien Reignault, Hans-Hermann Thulke, Wopke Van der Werf, Antonio Vicent Civera, Jonathan Yuen, Lucia Zappala, Andrea Battisti, Hugo Mas, Daniel Rigling, Olaf Mosbach-Schulz and Paolo Gonthier Abstract The European Commission requested the EFSA Panel on Plant Health to prepare and deliver risk assessments for commodities listed in Commission Implementing Regulation (EU) 2018/2019 as ‘High risk plants, plant products and other objects’. This Scientific Opinion covers all plant health risks posed by dormant and free of leaves, 1- to 3-year-old bare root plants for planting of Acer spp. imported from New Zealand, taking into account the available scientific information, including the technical information provided by New Zealand. The relevance of an EU-quarantine pest for this opinion was based on evidence that: (i) the pest is present in New Zealand; (ii) Acer spp. are hosts of the pest and (iii) the pest can be associated with the commodity. The relevance for this opinion of any other pest, not regulated in the EU, was based on evidence that: (i) the pest is present in New Zealand; (ii) the pest is absent from the EU; (iii) Acer spp. are hosts of the pest; (iv) the pest can be associated with the commodity and (v) the pest may have an impact and can pose a potential risk for the EU territory. -
Latitudinal Gradient in Leaf Defense Traits of Woody Plants Along Japanese Archipelago
Latitudinal gradient in leaf defense traits of woody plants along Japanese archipelago 日本産樹木種における、葉防御形質の緯度傾度 Saihanna 1 General Introduction It is estimated that over the twenty million species of organisms are living on our planet, and all of these organisms adapted to their own living environment, namely niche (Hatchinson 1957). Not only the abiotic factors but biotic interaction plays a key role in the maintenance of biodiversity. Animal-plant interactions are one of the most important topic in community ecology (e.g. Morin 1999). Plants and herbivore insects have accounted for about half of the entire diversity on the earth (Strong et al., 1984). Plant-herbivore interactions are extremely complex, which should lead the tremendous diversity of both plants and herbivores (e.g. Gutierrez et al., 1984; Hay et al., 1989). Although the interaction between these two components, namely co-speciation, should account for this diversification, most of the studies so far, tend to explain this interaction only from one side of them. Plants have interacted with insect herbivores for several hundred million years, which should lead to complex defense systems against various herbivores (Fürstenberg-Hägg et al., 2013). This interaction between plants and herbivores has long proposed the opportunity for studying the mechanism of the creation and maintenance of biological diversity because of its universality and generality (Strong et al. 1984; Ali and Agrawal 2012). It is believed that the evolution of plant defense traits followed by counter-adaptations in herbivores could lead to bursts of adaptive radiation of both components (Ehrlich and Raven 1969). Understanding the coevolution of plant and insect species and macroevolution of adaptive traits has inspired biologists for some decades, yet has been challenging to study even present days (Schluter, 2000). -
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. -
