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. -
2. ACER Linnaeus, Sp. Pl. 2: 1054. 1753. 枫属 Feng Shu Trees Or Shrubs
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. -
Abies Concolor (White Fir)
Compiled here is distribution, characteristics and other information on host species featured as ‘Host of the Month’ in past issues of the COMTF Monthly Report. Abies concolor (white fir) This is an evergreen tree native to the mountains of southern Oregon, California, the southern Rocky Mountains, and Baja California. Large and symmetrical, white fir grows 80 – 120ft tall and 15 – 20ft wide in its native range and in the Pacific Northwest. White fir is one of the top timber species found in the Sierra Nevada Mountains of CA and is a popular Christmas tree, as well as one of the most commonly grown native firs in Western gardens. Young trees are conical in shape, but develop a dome-like crown with age. The flattened needles of white fir are silvery blue-green, blunt at the tip , and grow 2 – 3in long. Often curving upwards, the needles extend at right angles from the twig, and twigs produce a citrus smell when needles are broken. White fir is monoecious, producing yellow- to red-toned, catkin-like male flowers and inconspicuous yellow-brown female flowers. The oblong cones grow 3 – 5 in upright, are yellow-green to purple in color, and are deciduous at maturity, dispersing seed in the fall. New twigs are dark- orange, but become gray-green, then gray with maturity. The bark of saplings is thin, smooth, and gray, turning thick, ash-gray with age, and developing deep irregular furrows. P. ramorum- infected Abies concolor (white fir) was first reported in the October 2005 COMTF newsletter as having been found at a Christmas tree farm in the quarantined county of Santa Clara. -

Nevertheless, trunks of A. pensylvanicum as they approach common names can offer intriguing clues about the rutting season, suggesting two additional plants and their formal, natural, and historical common names—moose maple and moose- associations. Consider the diversity of refer- wood.

Northern Hardwoods – Hemlock – White Pine Forest
Classification of the Natural Communities of Massachusetts Terrestrial Communities Descriptions Northern Hardwoods – Hemlock – White Pine Forest Community Code: CT1C000000 State Rank: S5 Concept: A matrix forest of northern areas, with a closed canopy dominated by a mix of deciduous and evergreen trees, with sparse shrub and herbaceous layers. Environmental Setting: The Northern Hardwoods - Hemlock - White Pine Forest is the prevailing, or matrix, forest in higher elevations of western and north-central Massachusetts, with smaller occurrences throughout on north-facing slopes and in ravines. It is an uneven-aged forest with a closed canopy dominated by a mix of long-lived deciduous and evergreen trees, with sparse shrub and herbaceous layers. The forest structure is dominated by single tree falls and replacements, with occasional small to medium blowdown events; stand replacement events are uncommon. The community occurs on neutral to moderately acidic soils with moderate levels of nutrients that retain some moisture except during extreme droughts. Sugar maple leaf litter is relatively high in nitrogen and decomposes rapidly which leads to a shallow layer of leaf litter and rapid turnover of nutrients. Vegetation Description: Dominant and characteristic species of Northern Hardwoods - Hemlock - White Pine Forests occur in different combinations between and within occurrences: occurrences are generally predominantly deciduous with scattered hemlocks and white pines, but may have internal patches of nearly pure conifers. Canopies include variable combinations of sugar maple (Acer saccharum), white ash (Fraxinus americana), yellow birch (Betula alleghaniensis), American beech (Fagus grandifolia), black cherry (Prunus serotina), red oak (Quercus rubra), bitternut hickory (Carya cordiformis), eastern hemlock (Tsuga canadensis), and, usually, emergent white pine (Pinus strobus). -
Wa Shan – Emei Shan, a Further Comparison
photograph © Zhang Lin A rare view of Wa Shan almost minus its shroud of mist, viewed from the Abies fabri forested slopes of Emei Shan. At its far left the mist-filled Dadu River gorge drops to 500-600m. To its right the 3048m high peak of Mao Kou Shan climbed by Ernest Wilson on 3 July 1903. “As seen from the top of Mount Omei, it resembles a huge Noah’s Ark, broadside on, perched high up amongst the clouds” (Wilson 1913, describing Wa Shan floating in the proverbial ‘sea of clouds’). Wa Shan – Emei Shan, a further comparison CHRIS CALLAGHAN of the Australian Bicentennial Arboretum 72 updates his woody plants comparison of Wa Shan and its sister mountain, World Heritage-listed Emei Shan, finding Wa Shan to be deserving of recognition as one of the planet’s top hotspots for biological diversity. The founding fathers of modern day botany in China all trained at western institutions in Europe and America during the early decades of last century. In particular, a number of these eminent Chinese botanists, Qian Songshu (Prof. S. S. Chien), Hu Xiansu (Dr H. H. Hu of Metasequoia fame), Chen Huanyong (Prof. W. Y. Chun, lead author of Cathaya argyrophylla), Zhong Xinxuan (Prof. H. H. Chung) and Prof. Yung Chen, undertook their training at various institutions at Harvard University between 1916 and 1926 before returning home to estab- lish the initial Chinese botanical research institutions, initiate botanical exploration and create the earliest botanical gardens of China (Li 1944). It is not too much to expect that at least some of them would have had personal encounters with Ernest ‘Chinese’ Wilson who was stationed at the Arnold Arboretum of Harvard between 1910 and 1930 for the final 20 years of his life. -
