Lonicera Periclymenum
''Lonicera periclymenum'', common names honeysuckle, common honeysuckle, European honeysuckle, or woodbine, is a species of flowering plant in the family Caprifoliaceae native to much of Europe, North Africa, Turkey and the Caucasus. It is found as far north as southern Norway and Sweden. Description Growing to or more in height, it is a vigorous deciduous twining climber, occasionally keeping its old leaves over winter. In the UK it is one of two native honeysuckles, the other being ''Lonicera xylosteum''. It is often found in woodland or in hedgerows or scrubland. The tubular, two-lipped flowers, creamy white or yellowish in colour, may be flushed with pink or red on the outside and in bud, and are carried in showy clusters at the ends of the shoots. The flowers are highly scented by night, much less so by day. Ecology The plant is usually pollinated by moths or long-tongued bees and develops bright red berries. Dormice make summer nests for their young from honeysuckle b ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Sorbus Aucuparia
''Sorbus aucuparia'', commonly called rowan (UK: /ˈrəʊən/, US: /ˈroʊən/) and mountain-ash, is a species of deciduous tree or shrub in the rose family. It is a highly variable species, and botanists have used different Circumscription (taxonomy), definitions of the species to include or exclude trees native to certain areas; a recent definition includes trees native to most of Europe and parts of Asia, as well as northern Africa. The range extends from Madeira, the British Isles and Iceland to Russia and northern China. Unlike many plants with similar distributions, it is not native to Japan. The tree has a slender trunk with smooth bark, a loose and roundish crown, and its leaves are pinnate in pairs of leaflets on a central vein with a terminal leaflet. It blossoms from May to June in dense corymbs of small yellowish white flowers and develops small red pomes as fruit that ripen from August to October and are eaten by many bird species. The plant is undemanding and frost h ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Senecio Jacobaea
''Jacobaea vulgaris'', syn. ''Senecio jacobaea'', is a very common wild flower in the family Asteraceae that is native to northern Eurasia, usually in dry, open places, and has also been widely distributed as a weed elsewhere. Common names include ragwort, common ragwort, smegplant, stinking willie, tansy ragwort, benweed, St. James-wort, stinking nanny/ninny/willy, staggerwort, dog standard, cankerwort, stammerwort. In the western United States it is generally known as tansy ragwort, or tansy, though its resemblance to the true tansy is superficial. In some countries it is an invasive species and regarded as a noxious weed. In the UK, where it is native, it is often unwanted because of its toxic effect for cattle and horses, but it is also valued for its nectar production which feeds insect pollinators and its ecological importance is thus considered significant. Description The plant is generally considered to be biennial but it has the tendency to exhibit perennial ...

Sambucus
''Sambucus'' is a genus of flowering plants in the family Adoxaceae. The various species are commonly called elder or elderberry. The genus was formerly placed in the honeysuckle family, Caprifoliaceae, but was reclassified as Adoxaceae due to genetic and morphological comparisons to plants in the genus ''Adoxa''. Description The oppositely arranged leaves are pinnate with 5–9 leaflets (or, rarely, 3 or 11). Each leaf is long, and the leaflets have serrated margins. They bear large clusters of small white or cream-colored flowers in late spring; these are followed by clusters of small black, blue-black, or red berries (rarely yellow or white).

Salix
Willows, also called sallows and osiers, from the genus ''Salix'', comprise around 400 speciesMabberley, D.J. 1997. The Plant Book, Cambridge University Press #2: Cambridge. of typically deciduous trees and shrubs, found primarily on moist soils in cold and temperate regions. Most species are known as willow, but some narrow-leaved shrub species are called osier, and some broader-leaved species are referred to as sallow (from Old English ''sealh'', related to the Latin word ''salix'', willow). Some willows (particularly arctic and alpine species) are low-growing or creeping shrubs; for example, the dwarf willow (''Salix herbacea'') rarely exceeds in height, though it spreads widely across the ground. Description Willows all have abundant watery bark sap, which is heavily charged with salicylic acid, soft, usually pliant, tough wood, slender branches, and large, fibrous, often stoloniferous roots. The roots are remarkable for their toughness, size, and tenacity to live, ... [...More Info...]       [...Related Items...]     OR:     [Wikipedia]   [Google]   [Baidu]   |

Rubus Idaeus
''Rubus idaeus'' (raspberry, also called red raspberry or occasionally European red raspberry to distinguish it from other raspberry species) is a red-fruited species of ''Rubus'' native to Europe and northern Asia and commonly cultivated in other temperate regions. Taxonomy A closely related plant in North America, sometimes regarded as the variety ''Rubus idaeus'' var. ''strigosus'', is more commonly treated as a distinct species, ''Rubus strigosus'' (American red raspberry), as is done here. Red-fruited cultivated raspberries, even in North America, are generally ''Rubus idaeus'' or horticultural derivatives of hybrids of ''R. idaeus'' and ''R. strigosus;'' these plants are all addressed in the present article. Description Plants of ''Rubus idaeus'' are generally perennials, which bear biennial stems ("canes") from a perennial root system. In its first year, a new, unbranched stem (" primocane") grows vigorously to its full height of 1.5–2.5 m (5.0–8.3 feet), bearing large ...

Rubus Fruticosus
''Rubus fruticosus'' L. is the ambiguous name of a European blackberry species in the genus ''Rubus'' in the rose family. The name has been interpreted in several ways: *The species represented by the type specimen of ''Rubus fruticosus'' L., which is also the type specimen of the genus ''Rubus''. This specimen is considered to match the species '' R. plicatus'', in ''Rubus'' subgenus ''Rubus'', section ''Rubus''. * Various species consistent with Linnaeus' original description of the species, which was based on a mixture of specimens now considered to match ''Rubus ulmifolius'' and ''R. plicatus'' *a species aggregate (group of similar species) ''Rubus fruticosus'' agg.

Rhododendron
''Rhododendron'' (; from Ancient Greek ''rhódon'' "rose" and ''déndron'' "tree") is a very large genus of about 1,024 species of woody plants in the heath family (Ericaceae). They can be either evergreen or deciduous. Most species are native to eastern Asia and the Himalayan region, but smaller numbers occur elsewhere in Asia, and in North America, Europe and Australia. It is the national flower of Nepal, the state flower of Washington and West Virginia in the United States, the state flower of Nagaland in India, the provincial flower of Jiangxi in China and the state tree of Sikkim and Uttarakhand in India. Most species have brightly colored flowers which bloom from late winter through to early summer. Azaleas make up two subgenera of ''Rhododendron''. They are distinguished from "true" rhododendrons by having only five anthers per flower.

Ranunculus
''Ranunculus'' is a large genus of about almost 1700 to more than 1800 species of flowering plants in the family Ranunculaceae. Members of the genus are known as buttercups, spearworts and water crowfoots. The genus is distributed in Europe, North America and South America. The familiar and widespread buttercup of gardens throughout Northern Europe (and introduced elsewhere) is the creeping buttercup ''Ranunculus repens'', which has extremely tough and tenacious roots. Two other species are also widespread, the bulbous buttercup ''Ranunculus bulbosus'' and the much taller meadow buttercup ''Ranunculus acris''. In ornamental gardens, all three are often regarded as weeds. Buttercups usually flower in the spring, but flowers may be found throughout the summer, especially where the plants are growing as opportunistic colonizers, as in the case of garden weeds. The water crowfoots (''Ranunculus'' subgenus ''Batrachium''), which grow in still or running water, are sometimes tr ...
