Maple Collection Maple Collection The Arnold Arboretum has an extensive collection of maples (Acer spp.), containing 141 of the approximately 230 maple taxa from around the world. Because of its diverse and numerous holdings of wild-collected maples, the Arnold Arboretum is designated as one of the North American Plant Collections Consortium’s maple collection sites. Our collection is especially rich in rare and unusual Asian maples, including a number of endangered species.

Several beautiful specimens of 1 three-flowered maple (Acer triflorum) grow in front of the Hunnewell Building. While many maples have simple leaves (think sugar maple or red maple), A. triflorum has compound leaves composed of three leaflets. This maple develops excellent orange to red fall color and has attractive amber bark that exfoliates in narrow curls. Just across the road from the Hunnewell Building is the original specimen of 2 Acer rubrum ‘Schlesingeri’, a red maple cultivar introduced by the Arnold Arboretum. It is one of the earliest red maple cultivars to show fall color, often as early as mid to late August. Over 100 feet tall and over 100 years old, the large 3 silver maple (Acer saccharinum, accession 12560-C) along Meadow Road is a favorite with visitors and is thought to be the tallest tree at the Arboretum. This tree survived the big hurricane of 1938 but did sustain some damage from Hurricane Irene in 2011. The genus Acer holds a number of interesting examples of North American-Asian disjunct flora (closely related, similar-looking species that grow on separate continents). Among the Arboretum’s maples, note the similarities between the striking stripe-barked (or snake-bark) maples from Asia (including 4 A. tegmentosum, 5 A. davidii, pictured at left, and 6 A. capillipes) and 7 A. pensylvanicum (commonly known as striped maple or moosewood) from eastern North America. The maple collection holds accessions of 8 Japanese maple (Acer palmatum), pictured at right, and its cultivars, which are popular small ornamental trees. Similarly handsome species in the collection include 9 A. pseudosieboldianum, 10 A. japonicum, 11 A. mono, and 12 A. pubipalmatum. 13 Paperbark maple (Acer griseum) has long been favored by plant connoisseurs for its lovely exfoliating, cinnamon-colored bark and bright red-orange fall color. The Arboretum holds two of the first paperbark maples in the United States, grown from seed wild-collected in China by E. H. Wilson in 1907; look for one venerable specimen in the heart of the maple collection, and a unique, wide- spreading specimen in the Explorers Garden on Bussey Hill..

  • 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.

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.

  • Native Or Suitable Plants City of Mccall
    Native or Suitable Plants City of McCall The following list of plants is presented to assist the developer, business owner, or homeowner in selecting plants for landscaping. The list is by no means complete, but is a recommended selection of plants which are either native or have been successfully introduced to our area. Successful landscaping, however, requires much more than just the selection of plants. Unless you have some experience, it is suggested than you employ the services of a trained or otherwise experienced landscaper, arborist, or forester. For best results it is recommended that careful consideration be made in purchasing the plants from the local nurseries (i.e. Cascade, McCall, and New Meadows). Plants brought in from the Treasure Valley may not survive our local weather conditions, microsites, and higher elevations. Timing can also be a serious consideration as the plants may have already broken dormancy and can be damaged by our late frosts. Appendix B SELECTED IDAHO NATIVE PLANTS SUITABLE FOR VALLEY COUNTY GROWING CONDITIONS Trees & Shrubs Acer circinatum (Vine Maple). Shrub or small tree 15-20' tall, Pacific Northwest native. Bright scarlet-orange fall foliage. Excellent ornamental. Alnus incana (Mountain Alder). A large shrub, useful for mid to high elevation riparian plantings. Good plant for stream bank shelter and stabilization. Nitrogen fixing root system. Alnus sinuata (Sitka Alder). A shrub, 6-1 5' tall. Grows well on moist slopes or stream banks. Excellent shrub for erosion control and riparian restoration. Nitrogen fixing root system. Amelanchier alnifolia (Serviceberry). One of the earlier shrubs to blossom out in the spring.

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.

  • 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.
