Salvia Patens
''Salvia patens'', the gentian sage or spreading sage, is a species of flowering plant in the sage family Lamiaceae that is native to a wide area of central Mexico. This herbaceous perennial was introduced into horticulture in 1838 and popularized a hundred years later by the Irish gardener and botanist William Robinson (1838-1935). Description ''Salvia patens'' is tuberous, and easily lifted for overwintering in a greenhouse. The more common varieties reach tall and wide, and are covered with hastate shaped mistletoe-green leaves. Inflorescences reach or longer, rising well above the leaves. pure blue flowers are spaced along the inflorescence, with a green calyx that adds to the attractiveness of the flowers. The Latin specific epithet ''patens'' means "spreading". Cultivation ''Salvia patens'' is frequently treated as an annual by gardeners due to its sensitivity to hard frost, with bedding plants often put out in spring. Varieties have been developed with colors ranging ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Antonio José Cavanilles
Antonio José Cavanilles (16 January 1745 – 5 May 1804) was a leading Spanish taxonomic botanist, artist and one of the most important figures in the 18th century period of Enlightenment in Spain. Cavanilles is most famous for his 2-volume book on Spanish flora, published in 1795 and titled ‘Observations on the Natural History, Geography and Agriculture of the Kingdom of Valencia’.He named many plants, particularly from Oceania. He named at least 100 genera, about 54 of which were still used in 2004, including ''Dahlia'', '' Calycera'', '' Cobaea'', '' Galphimia'', and '' Oleandra''. Biography Cavanilles was born in Valencia. He lived in Paris from 1777 to 1781, where he followed careers as a clergyman and a botanist, thanks to André Thouin and Antoine Laurent de Jussieu. He was one of the first Spanish scientists to use the classification method invented by Carl Linnaeus. Early life and education Antonio José Cavanilles was born on January 16, 1745, in Valenc ...

Species
A species () is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can produce fertile offspring, typically by sexual reproduction. It is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour, or ecological niche. In addition, palaeontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. About 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomen". The first part of a binomen is the name of a genus to which the species belongs. The second part is called the specific name (zoology), specific name or the specific ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (). The term angiosperm is derived from the Ancient Greek, Greek words (; 'container, vessel') and (; 'seed'), meaning that the seeds are enclosed within a fruit. The group was formerly called Magnoliophyta. Angiosperms are by far the most diverse group of Embryophyte, land plants with 64 Order (biology), orders, 416 Family (biology), families, approximately 13,000 known Genus, genera and 300,000 known species. They include all forbs (flowering plants without a woody Plant stem, stem), grasses and grass-like plants, a vast majority of broad-leaved trees, shrubs and vines, and most aquatic plants. Angiosperms are distinguished from the other major seed plant clade, the gymnosperms, by having flowers, xylem consisting of vessel elements instead of tracheids, endosperm within their seeds, and fruits that completely envelop the seeds. The ancestors of flowering plants diverged from the commo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (botany)
Family (, : ) is one of the eight major hierarchical taxonomic ranks in Linnaean taxonomy. It is classified between order and genus. A family may be divided into subfamilies, which are intermediate ranks between the ranks of family and genus. The official family names are Latin in origin; however, popular names are often used: for example, walnut trees and hickory trees belong to the family Juglandaceae, but that family is commonly referred to as the "walnut family". The delineation of what constitutes a family—or whether a described family should be acknowledged—is established and decided upon by active taxonomists. There are not strict regulations for outlining or acknowledging a family, yet in the realm of plants, these classifications often rely on both the vegetative and reproductive characteristics of plant species. Taxonomists frequently hold varying perspectives on these descriptions, leading to a lack of widespread consensus within the scientific community for ...

Herbaceous
Herbaceous plants are vascular plants that have no persistent woody stems above ground. This broad category of plants includes many perennials, and nearly all annuals and biennials. Definitions of "herb" and "herbaceous" The fourth edition of the '' Shorter Oxford English Dictionary'' defines "herb" as: # "A plant whose stem does not become woody and persistent (as in a tree or shrub) but remains soft and succulent, and dies (completely or down to the root) after flowering"; # "A (freq. aromatic) plant used for flavouring or scent, in medicine, etc.". (See: Herb) The same dictionary defines "herbaceous" as: # "Of the nature of a herb; esp. not forming a woody stem but dying down to the root each year"; # "BOTANY Resembling a leaf in colour or texture. Opp. scarious". Botanical sources differ from each other on the definition of "herb". For instance, the Hunt Institute for Botanical Documentation includes the condition "when persisting over more than one growing season, the ...

Perennial Plant
In horticulture, the term perennial (''wikt:per-#Prefix, per-'' + ''wikt:-ennial#Suffix, -ennial'', "through the year") is used to differentiate a plant from shorter-lived annual plant, annuals and biennial plant, biennials. It has thus been defined as a plant that lives more than 2 years. The term is also loosely used to distinguish plants with little or no woody growth (secondary growth in Tree girth measurement, girth) from trees and shrubs, which are also technically ''perennials''. Notably, it is estimated that 94% of plant species fall under the category of perennials, underscoring the prevalence of plants with lifespans exceeding two years in the botanical world. Perennials (especially small flowering plants) that grow and bloom over the spring and summer, die back every autumn and winter, and then return in the spring from their rootstock or other overwintering structure, are known as Herbaceous plant, herbaceous perennials. However, depending on the rigours of the loca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
William Robinson (gardener)
William Robinson: (15 July 1838 – 12 May 1935) was an Irish practical gardener and journalist whose ideas about wild gardening spurred the movement that led to the popularising of the English cottage garden, a parallel to the search for honest simplicity and vernacular style of the British Arts and Crafts movement, and were important in promoting the woodland garden. Robinson is credited as an early practitioner of the mixed herbaceous border of hardy perennial plants, a champion too of the "wild garden", who vanquished the high Victorian pattern garden of planted-out bedding schemes. Robinson's new approach to gardening gained popularity through his magazines and several books—particularly ''The Wild Garden'', illustrated by Alfred Parsons, and ''The English Flower Garden''. Robinson advocated more natural and less formal-looking plantings of hardy perennials, shrubs, and climbers, and reacted against the High Victorian patterned gardening, which used tropical mat ...
