Catalpa × Erubescens
''Catalpa'' × ''erubescens'' (or ''Catalpa erubescens''), the hybrid catalpa, is a hybrid plant species of ''Catalpa'' in the family Bignoniaceae. It is a medium-sized tree, reaching at most 20m. Its parents are southern catalpa, ''Catalpa bignonioides'', from the United States, and yellow catalpa, '' C. ovata'', from China. There is one accepted form, ''Catalpa × erubescens'' Carrière f. ''purpurea'' (Wawra & Abel) Paclt, which has purple, some say chocolate-colored, young leaves which turn green as they mature. This form is marketed under a variety of names, such as hybrid catalpa 'Purpurea', red-leaved Indian bean tree, and purple hybrid catalpa, and has gained the Royal Horticultural Society's Award of Garden Merit The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS).

Élie-Abel Carrière
Élie-Abel Carrière (4 June 1818 – 17 August 1896) was a French botanist, based in Paris. He was a leading authority on conifers in the period 1850–1870, describing many new species, and the new genera ''Tsuga'', ''Keteleeria'' and ''Pseudotsuga''. His most important work was the ''Traité Général des Conifères'', published in 1855, with a second, extensively revised edition in 1867. There is a brief biography of Carrière, in English, in the journal ''Brittonia''. In addition to his studies of conifers, he published a number of works in the field of horticulture: * ''Guide pratique du jardinier multiplicateur: ou art de propager les végétaux par semis, boutures, greffes, etc''. (1856)-- book on propagation of plants by seeds, cuttings, grafts. * ''Flore des jardins de l'Europe: manuel général des plantes, arbres et arbustes, comprenant leur origine, description, culture : leur application aux jardins d'agrément, à l'agriculture, aux forêts, aux usages dome ...

Catalpa
''Catalpa'', commonly called catalpa or catawba, is a genus of flowering plants in the family Bignoniaceae, native to warm temperate and subtropical regions of North America, the Caribbean, and East Asia. Description Most ''Catalpa'' are deciduous trees; they typically grow to tall, with branches spreading to a diameter of about . They are fast growers and a 10-year-old sapling may stand about tall. They have characteristic large, heart-shaped leaves, which in some species are three-lobed. The appearance of the leaves sometimes causes confusion with species such as the unrelated tung tree (''Vernicia fordii'') and ''Paulownia tomentosa''. ''Catalpa'' species bear broad panicles of showy flowers, generally in summer. The flower colour generally is white to yellow. In late summer or autumn the fruit appear; they are siliques about long, full of small flat seeds, each with two thin wings to aid in wind dispersal. The large leaves and dense foliage of ''Catalpa'' species provide ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Catalpa Bignonioides
''Catalpa bignonioides'' is a species of '' Catalpa'' that is native to the southeastern United States in Alabama, Florida, Georgia, Louisiana, and Mississippi. Common names include southern catalpa, cigartree, and Indian-bean-tree (or Indian bean tree). It is commonly used as a garden and street tree. Description It is a medium-sized deciduous tree growing to tall, with a trunk up to diameter, with brown to gray bark, maturing into hard plates or ridges. The short thick trunk supports long and straggling branches which form a broad and irregular head. The roots are fibrous and branches are brittle, its juices are watery and bitter tasting. The leaves are large, bright green and heart shaped, being long and broad. They appear late, and as they are full-grown before the flower clusters open, they add much to the beauty of the blossoming tree. They secrete nectar, a most unusual characteristic for leaves, by means of groups of tiny glands in the axils of the primary veins. ...

Catalpa Ovata
''Catalpa ovata'', the yellow catalpa or Chinese catalpa (), is a pod-bearing tree native to China. Compared to ''C. speciosa'', it is much smaller, typically reaching heights between . The inflorescences form bunches of creamy white flowers with distinctly yellow tinging; individual flowers are about wide. They bloom in July and August. The leaves are very similar in shape to those of ''Paulownia tomentosa'', having three lobes (two are abruptly truncated on either edge, with a third, central, slightly acute, pointed lobe forming the leaf apex), and are darkly green. Fruits are very narrow, foot-long pods. Although native to the more temperate provinces within China (Anhui, Gansu, Hebei, Heilongjiang, Henan, Hubei, Jiangsu, Jilin, Liaoning, Nei Monggol, Ningxia, Qinghai, Shaanxi, Shandong, Shanxi, Sichuan, Xinjiang), ''C. ovata'' is also cultivated in North America and Europe, and has become a parent of ''Catalpa × erubescens'' with the American species ''Catalpa bignonioide ...

Award Of Garden Merit
The Award of Garden Merit (AGM) is a long-established annual award for plants by the British Royal Horticultural Society (RHS). It is based on assessment of the plants' performance under UK growing conditions. History The Award of Garden Merit is a mark of quality awarded, since 1922, to garden plants (including trees, vegetables and decorative plants) by the United Kingdom, Royal Horticultural Society (RHS). Awards are made annually after plant trials intended to judge the plants' performance under UK growing conditions. Trials may last for one or more years, depending on the type of plant being analyzed, and may be performed at Royal Horticulture Society Garden in Wisley and other gardens or after observation of plants in specialist collections. Trial reports are made available as booklets and on the website. Awards are reviewed annually in case plants have become unavailable horticulturally, or have been superseded by better cultivars. Similar awards The award should not be ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ornamental Trees
Ornamental plants or garden plants are plants that are primarily grown for their beauty but also for qualities such as scent or how they shape physical space. Many flowering plants and garden varieties tend to be specially bred cultivars that improve on the original species in qualities such as color, shape, scent, and long-lasting blooms. There are many examples of fine ornamental plants that can provide height, privacy, and beauty for any garden. These ornamental perennial plants have seeds that allow them to reproduce. One of the beauties of ornamental grasses is that they are very versatile and low maintenance. Almost any types of plant have ornamental varieties: trees, shrubs, climbers, grasses, succulents. aquatic plants, herbaceous perennials and annual plants. Non-botanical classifications include houseplants, bedding plants, hedges, plants for cut flowers and foliage plants. The cultivation of ornamental plants comes under floriculture and tree nurseries, which is a ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Plants Described In 1869
Plants are predominantly photosynthetic eukaryotes of the kingdom Plantae. Historically, the plant kingdom encompassed all living things that were not animals, and included algae and fungi; however, all current definitions of Plantae exclude the fungi and some algae, as well as the prokaryotes (the archaea and bacteria). By one definition, plants form the clade Viridiplantae (Latin name for "green plants") which is sister of the Glaucophyta, and consists of the green algae and Embryophyta (land plants). The latter includes the flowering plants, conifers and other gymnosperms, ferns and their allies, hornworts, liverworts, and mosses. Most plants are multicellular organisms. Green plants obtain most of their energy from sunlight via photosynthesis by primary chloroplasts that are derived from endosymbiosis with cyanobacteria. Their chloroplasts contain chlorophylls a and b, which gives them their green color. Some plants are parasitic or mycotrophic and have lost the ability ...
