Calcifuge
A calcifuge is a plant that does not tolerate alkaline (basic) soil. The word is derived from the Latin 'to flee from chalk'. These plants are also described as ericaceous, as the prototypical calcifuge is the genus '' Erica'' (heaths). It is not the presence of carbonate or hydroxide ions ''per se'' that these plants cannot tolerate, but the fact that under alkaline conditions, iron becomes less soluble. Consequently, calcifuges grown on alkaline soils often develop the symptoms of iron deficiency, ''i.e.'' interveinal chlorosis of new growth. There are many horticultural plants which are calcifuges, most of which require an 'ericaceous' compost with a low pH, composed principally of ''Sphagnum'' moss peat. Alternatively sulphur chips may be used to lower soil pH. A plant that thrives in lime-rich soils is known as a calcicole.

Erica (plant)
''Erica'' is a genus of roughly 857 species of flowering plants in the family Ericaceae. The English common names heath and heather are shared by some closely related genera of similar appearance. The genus '' Calluna'' was formerly included in ''Erica'' – it differs in having even smaller scale-leaves (less than 2–3 millimetres long), and the flower corolla consisting of separate petals. ''Erica'' is sometimes referred to as "winter (or spring) heather" to distinguish it from ''Calluna'' "summer (or autumn) heather". Description Most of the species of ''Erica'' are small shrubs from high, though some are taller; the tallest are '' E. arborea'' (tree heath) and '' E. scoparia'' (besom heath), both of which can reach up to tall. All are evergreen, with minute, needle-like leaves long. Flowers are sometimes axillary, and sometimes borne in terminal umbels or spikes, and are usually outward or downward facing. The seeds are very small, and in some species may survi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Rhododendron
''Rhododendron'' (; : ''rhododendra'') is a very large genus of about 1,024 species of woody plants in the Ericaceae, 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 List of U.S. state and territory flowers, state flower of Washington (state), Washington and West Virginia in the United States, the state flower of Nagaland and Himachal Pradesh in India, the provincial flower of Jeju Province in South Korea, the provincial flower of Jiangxi in China and the List of Indian state trees, state tree of Sikkim and Uttarakhand in India. Most species have brightly coloured 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. E ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Andromeda Polifolia
''Andromeda polifolia'', common name bog-rosemary, is a species of flowering plant in the heath family Ericaceae, native to northern parts of the Northern Hemisphere. It is the only member of the genus ''Andromeda'', and is only found in bogs in cold peat-accumulating areas. ''Andromeda glaucophylla'' is a synonym of ''A. polifolia'' var. ''latifolia''.

Carnivorous Plant
Carnivorous plants are plants that derive some or most of their nutrients from trapping and consuming animals or protozoans, typically insects and other arthropods, and occasionally small mammals and birds. They have adapted to grow in waterlogged sunny places where the soil is thin or poor in nutrients, especially nitrogen, such as acidic bogs. They can be found on all continents except Antarctica, as well as many Pacific islands. In 1875, Charles Darwin published '' Insectivorous Plants'', the first treatise to recognize the significance of carnivory in plants, describing years of painstaking research. True carnivory is believed to have evolved independently at least 12 times in five different orders of flowering plants, and is represented by more than a dozen genera. This classification includes at least 583 species that attract, trap, and kill prey, absorbing the resulting available nutrients. Venus flytraps (''Dionaea muscipula''), pitcher plants, and bladderworts ('' ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Erica Carnea
''Erica carnea'', the winter heath, winter-flowering heather, spring heath or alpine heath, is a species of flowering plant in the family (biology), family Ericaceae, native plant, native to mountainous areas of central, eastern and southern Europe, where it grows in Pinophyta, coniferous woodlands or stony slopes. Description It is a low-growing, spreading subshrub reaching tall, with evergreen needle-like leaves long, borne in whorls of four. The flowers are produced in racemes in late winter to early spring, often starting to flower while the plant is still covered in snow; the individual flower is a slender bell-shape, long, dark reddish-pink, rarely white. Taxonomy The first published name for the species was ''Erica herbacea''; however, the name ''E. carnea'' (published three pages later in the same book) is so widely used, and the earlier name so little, that a formal proposal to conserve the name ''E. carnea'' over ''E. herbacea'' was accepted by the International Bota ...

Calcicole
A calcicole, calciphyte or calciphile is a plant that thrives in lime rich soil. The word is derived from the Latin 'to dwell on chalk'. Under acidic conditions, aluminium becomes more soluble and phosphate less. As a consequence, calcicoles grown on acidic soils often develop the symptoms of aluminium toxicity, i.e. necrosis, and phosphate deficiency, i.e. anthocyanosis (reddening of the leaves) and stunting. A plant that thrives in acid soils is known as a calcifuge. A plant thriving on sand (which may be acidic or calcic) is termed psammophilic or arenaceous (see also arenite). Examples of calcicole plants * Ash trees (''Fraxinus'' spp.) * Honeysuckle ('' Lonicera'') * ''Buddleja'' * Lilac ('' Syringa'') * Beet * ''Clematis'' * '' Sanguisorba minor'' * Some European orchids * Some succulent plant In botany, succulent plants, also known as succulents, are plants with parts that are thickened, fleshy, and engorged, usually to retain water in arid climates or soil condit ...

Plant
Plants are the eukaryotes that form the Kingdom (biology), kingdom Plantae; they are predominantly Photosynthesis, photosynthetic. This means that they obtain their energy from sunlight, using chloroplasts derived from endosymbiosis with cyanobacteria to produce sugars from carbon dioxide and water, using the green pigment chlorophyll. Exceptions are parasitic plants that have lost the genes for chlorophyll and photosynthesis, and obtain their energy from other plants or fungi. Most plants are multicellular organism, multicellular, except for some green algae. Historically, as in Aristotle's biology, the plant kingdom encompassed all living things that were not animals, and included algae and fungi. Definitions have narrowed since then; current definitions exclude fungi and some of the algae. By the definition used in this article, plants form the clade Viridiplantae (green plants), which consists of the green algae and the embryophytes or land plants (hornworts, liverworts ...
