Pachysandra
''Pachysandra'' is a genus of five species of evergreen perennials or subshrubs, belonging to the boxwood family Buxaceae. The species are native to eastern Asia and southeast North America, some reaching a height of , with only weakly woody stems. The leaves are alternate, leathery, with a coarsely toothed margin, and are typically long. The small uni-sexual blooms are greenish-white and produced in late spring or early summer. Etymology ''Pachysandra'' is derived from the Ancient Greek word παχύς (''pachýs'', 'thick') and the New Latin ''-androus'' ('of or pertaining to stamens'), and is a reference to the thick stamens.Gledhill, David (2008).

Pachysandra Procumbens
''Pachysandra procumbens'', the Allegheny pachysandra or Allegheny spurge, is a flowering plant in the family Buxaceae, native to the southeast United States from West Virginia and Kentucky south to Florida, and west to Louisiana. The name ''Allegheny'' is sometimes spelled ''Alleghany''. It is an evergreen subshrub, growing to at most 30 cm high, usually less. The leaves are 5–10 cm long, with a coarsely toothed margin. The flowers are small, white, produced several together on a terminal raceme A raceme ( or ) or racemoid is an unbranched, indeterminate type of inflorescence bearing flowers having short floral stalks along the shoots that bear the flowers.

Pachysandra Terminalis
''Pachysandra terminalis'', the Japanese pachysandra, carpet box or Japanese spurge, is a species of flowering plant in the boxwood family Buxaceae, native to Japan, Korea and China and introduced to eastern North America. It is a slow-growing, spreading evergreen perennial growing to tall by broad, with alternate, simple, glossy leaves, and creeping stems. The leaves may yellow in direct sunlight or in winter. When growing in a spreading mass of many plants, a dense cover is formed. The flowers are white, borne above the foliage. In temperate Northern Hemisphere sites they appear late in the month of March and throughout the month of April. The plant is very cold hardy. The specific epithet ''terminalis'' means "ending", and refers to the clusters of leaves which appear at the end of the short stems. Cultivation ''Pachysandra terminalis'' is cultivated as an ornamental plant, for use as a massed groundcover, low grouped element, or accent plant in the ground. It is a suit ...

Buxaceae
The Buxaceae are a small family of six genera and about 123 known species of flowering plants. They are shrubs and small trees, with a cosmopolitan distribution. A seventh genus, sometimes accepted in the past (''Notobuxus''), has been shown by genetic studies to be included within ''Buxus'' (Balthazar ''et al.'', 2000). The family is recognised by most taxonomists, and it is commonly known as the box family. However, its placement and circumscription has varied; some taxonomists treated '' Styloceras'' in its own family Stylocerataceae, ''Didymeles'' in its own family Didymelaceae, ''Haptanthus'' in Haptanthaceae (now all included in Buxaceae)), and formerly '' Simmondsia'' was included, which is not related and now usually placed in its own family Simmondsiaceae. The APG II system of 2003 recognises the family, but in a new circumscription in that it includes the genus ''Didymeles'' (two species of evergreen trees from Madagascar). However, APG II does allow the option of segr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ground Cover
Groundcover or ground cover is any plant that grows over an area of ground. Groundcover provides protection of the topsoil from erosion and drought. In an ecosystem, the ground cover forms the layer of vegetation below the shrub layer known as the herbaceous layer. The most widespread ground covers are grasses of various types. In ecology, groundcover is a difficult subject to address because it is known by several different names and is classified in several different ways. The term groundcover could also be referring to “the herbaceous layer,” “regenerative layer", “ground flora” or even "step over." In agriculture, ground cover refers to anything that lies on top of the soil and protects it from erosion and inhibits weeds. It can be anything from a low layer of grasses to a plastic material. The term ''ground cover'' can also specifically refer to landscaping fabric which is like a breathable tarp that allows water and gas exchange. In gardening jargon, however, ...

Humus
In classical soil science, humus is the dark organic matter in soil that is formed by the decomposition of plant and animal matter. It is a kind of soil organic matter. It is rich in nutrients and retains moisture in the soil. Humus is the Latin word for "earth" or "ground". In agriculture, "humus" sometimes also is used to describe mature or natural compost extracted from a woodland or other spontaneous source for use as a soil conditioner. It is also used to describe a topsoil horizon that contains organic matter (''humus type'', ''humus form'', or ''humus profile''). Humus has many nutrients that improve the health of soil, nitrogen being the most important. The ratio of carbon to nitrogen (C:N) of humus commonly ranges between eight and fifteen with the median being about twelve. It also significantly affects the bulk density of soil. Humus is amorphous and lacks the "cellular cake structure characteristic of plants, micro-organisms or animals". Description The primary ...

Shade Gardens
Shade gardens are a type of garden planted and grown in areas with little or no direct sunlight. Shade gardens may occur naturally or by design under trees, as well as on the side of buildings or fences. This style of garden presents certain challenges, in part because only certain plants are able to grow in shady conditions and otherwise there is direct competition for sunlight. Very few edible plants grow well in shady conditions, so shade gardens are usually ornamental gardens, though growing flowers may also be difficult in shade. Light shade, also known as "dappled sunlight", may support growing herbs or some leaf vegetables, but in addition to lack of light, trees and other large plants which create shade gardens may negatively impact soil fertility.

Variety (botany)
In botanical nomenclature, variety (abbreviated var.; in la, varietas) is a taxonomic rank below that of species and subspecies, but above that of form. As such, it gets a three-part infraspecific name. It is sometimes recommended that the subspecies rank should be used to recognize geographic distinctiveness, whereas the variety rank is appropriate if the taxon is seen throughout the geographic range of the species. Example The pincushion cactus, ''Escobaria vivipara'' (Nutt.) Buxb., is a wide-ranging variable species occurring from Canada to Mexico, and found throughout New Mexico below about . Nine varieties have been described. Where the varieties of the pincushion cactus meet, they intergrade. The variety ''Escobaria vivipara'' var. ''arizonica'' is from Arizona, while ''Escobaria vivipara'' var. ''neo-mexicana'' is from New Mexico. See also '' Capsicum annuum var. glabriusculum'' Definitions The term is defined in different ways by different authors. However, the I ...

Sarcococca
''Sarcococca'' (sweet box or Christmas box) is a genus of 11 species of flowering plants in the box family (biology), family Buxaceae, native plant, native to eastern and southeastern Asia and the Himalayas. They are slow-growing, monoecious, evergreen shrubs tall. The leaf, leaves are borne alternately, 3–12 cm long and 1–4 cm broad. The plants bear fragrant white flowers, often in winter. The fruit is a red or black drupe containing 1–3 seeds. Some species are cultivated as groundcover or low hedging in moist, shady areas. The basic chromosome number for genus is 14 (2n = 28). The genus name ''Sarcococca'' comes from the Greek σάρξ (''sárx'') and κόκκος (''kókkos'') for "fleshy berry", referring to the black fruit.

Genus
Genus ( plural genera ) is a taxonomic rank used in the biological classification of extant taxon, living and fossil organisms as well as Virus classification#ICTV classification, viruses. In the hierarchy of biological classification, genus comes above species and below family (taxonomy), family. In binomial nomenclature, the genus name forms the first part of the binomial species name for each species within the genus. :E.g. ''Panthera leo'' (lion) and ''Panthera onca'' (jaguar) are two species within the genus ''Panthera''. ''Panthera'' is a genus within the family Felidae. The composition of a genus is determined by taxonomy (biology), taxonomists. The standards for genus classification are not strictly codified, so different authorities often produce different classifications for genera. There are some general practices used, however, including the idea that a newly defined genus should fulfill these three criteria to be descriptively useful: # monophyly – all descendants ...
