Glandora Diffusa
''Glandora diffusa'', the purple gromwell, syn. ''Lithodora diffusa'', ''Lithospermum diffusa'', is a species of flowering plant in the family Boraginaceae. It is a mat-forming perennial growing to tall by or more wide, with dark green, hairy evergreen leaves and masses of blue or white 5-lobed flowers. It is suitable for cultivation in a rock garden or alpine garden. Although there is a variety with white flowers, ''G. diffusa'' var. ''alba'', the blue-flowered varieties are most valued in gardens for the intense azure color of their abundant blooms. A number of cultivars have been developed for garden use. ''Glandora diffusa'' is hardy down to (USDA zones 6 - 8), and requires a position in full sun. It needs a well-drained acid or neutral soil, as it is susceptible to root rot. It requires vernalization Vernalization (from Latin ''vernus'', "of the spring") is the induction of a plant's flowering process by exposure to the prolonged cold of winter, or by an artificial ...

Mariano Lagasca
Mariano Lagasca y Segura (1776–1839), also known as Mariano la Gasca, was a Spanish botanist, writer and doctor. He was the director of the ''Real Jardín Botánico de Madrid'' (Royal Botanical Garden of Madrid). Early life Mariano Lagasca y Segura was born in Encinacorba, Province of Zaragoza, in Spain on 4 October 1776 to a wealthy Catholic family. He studied at the local elementary school and, afterwards, he continued his ecclesiastical studies in Tarragona. During his studies in Tarragona, he developed an interest for medicine and botany. After finishing his studies in Tarragona, he started travelling until eventually studying medicine at first in Zaragoza, and later in Valencia and Madrid. Career In 1800, he moved to Madrid where he met Antonio José Cavanilles, a well-known botanist and doctor and became his disciple. In Madrid, he cooperated in various fields José Demetrio Rodriguez, and co-published with him a botanical book titled Description of certain pl ...

Ivan Murray Johnston
I. M. (Ivan Murray) Johnston (February 28, 1898–May 31, 1960), was a United States Botany, botanist. He studied at Pomona College in Claremont, California and at Harvard University. His plant collections are housed in the ''Rancho Santa Ana Botanic Garden'', in Claremont, and also in the ''Gray Herbarium'' of Harvard University. His areas of interest, were, among others: Fern, Pteridophytes, Spermatophytes Honours In 1925, German botanist August Brand, named a genus of flowering plants (belonging to the family Boraginaceae), from South America and southern states in USA, as ''Johnstonella'' in his honour. Then in 1933, botanist O.E.Schulz named a genus of flowering plants (belonging to the family Brassicaceae), from Chile as ''Ivania (plant), Ivania''. In 1936, botanist Hsen Hsu Hu published ''Sinojohnstonia'', which is a genus of flowering plants from China, belonging to the family Boraginaceae.

Synonym (taxonomy)
The Botanical and Zoological Codes of nomenclature treat the concept of synonymy differently. * In botanical nomenclature, a synonym is a scientific name that applies to a taxon that (now) goes by a different scientific name. For example, Linnaeus was the first to give a scientific name (under the currently used system of scientific nomenclature) to the Norway spruce, which he called ''Pinus abies''. This name is no longer in use, so it is now a synonym of the current scientific name, ''Picea abies''. * In zoology, moving a species from one genus to another results in a different binomen, but the name is considered an alternative combination rather than a synonym. The concept of synonymy in zoology is reserved for two names at the same rank that refers to a taxon at that rank - for example, the name ''Papilio prorsa'' Linnaeus, 1758 is a junior synonym of ''Papilio levana'' Linnaeus, 1758, being names for different seasonal forms of the species now referred to as ''Araschnia le ...

Species
In biology, a species is the basic unit of classification and a taxonomic rank of an organism, as well as a unit of biodiversity. 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. Other ways of defining species include their karyotype, DNA sequence, morphology, behaviour or ecological niche. In addition, paleontologists 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. However, only about 14% of these had been described by 2011. All species (except viruses) are given a two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Family (biology)
Family ( la, familia, plural ') 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". What belongs to a family—or if a described family should be recognized at all—are proposed and determined by practicing taxonomists. There are no hard rules for describing or recognizing a family, but in plants, they can be characterized on the basis of both vegetative and reproductive features of plant species. Taxonomists often take different positions about descriptions, and there may be no broad consensus across the scientific community for some time. The publishing of new data and opini ...

Perennial Plant
A perennial plant or simply perennial is a plant that lives more than two years. The term ('' per-'' + '' -ennial'', "through the years") is often used to differentiate a plant from shorter-lived annuals and biennials. The term is also widely used to distinguish plants with little or no woody growth (secondary growth in girth) from trees and shrubs, which are also technically perennials. Perennialsespecially small flowering plantsthat 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 perennials. However, depending on the rigours of local climate (temperature, moisture, organic content in the soil, microorganisms), a plant that is a perennial in its native habitat, or in a milder garden, may be treated by a gardener as an annual and planted out every year, from seed, from cuttings, or from divisions. Tomato vines, for example, live several y ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evergreen
In botany, an evergreen is a plant which has foliage that remains green and functional through more than one growing season. This also pertains to plants that retain their foliage only in warm climates, and contrasts with deciduous plants, which completely lose their foliage during the winter or dry season. Evergreen species There are many different kinds of evergreen plants, both trees and shrubs. Evergreens include: *Most species of conifers (e.g., pine, hemlock, blue spruce, and red cedar), but not all (e.g., larch) *Live oak, holly, and "ancient" gymnosperms such as cycads *Most angiosperms from frost-free climates, and rainforest trees *All Eucalypts * Clubmosses and relatives *Bamboos The Latin binomial term , meaning "always green", refers to the evergreen nature of the plant, for instance :'' Cupressus sempervirens'' (a cypress) :''Lonicera sempervirens'' (a honeysuckle) :''Sequoia sempervirens'' (a sequoia) Leaf longevity in evergreen plants varies from a few months ...

Rock Garden
A rock garden, also known as a rockery and formerly as a rockwork, is a garden, or more often a part of a garden, with a landscaping framework of rocks, stones, and gravel, with planting appropriate to this setting. Usually these are small Alpine plants that need relatively little soil or water. Western rock gardens are often divided into alpine gardens, scree gardens on looser, smaller stones, and other rock gardens. Some rock gardens are planted around natural outcrops of rock, perhaps with some artificial landscaping, but most are entirely artificial, with both rocks and plants brought in. Some are designed and built to look like natural outcrops of bedrock. Stones are aligned to suggest a bedding plane, and plants are often used to conceal the joints between said stones. This type of rockery was popular in Victorian times and usually created by professional landscape architects. The same approach is sometimes used in commercial or modern-campus landscaping but can also ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Alpine Garden
An alpine garden (or alpinarium, alpinum) is a domestic or botanical garden, or more often a part of a larger garden, specializing in the collection and cultivation of alpine plants growing naturally at high altitudes around the world, such as in the Caucasus, Pyrenees, Rocky Mountains, Alps, Himalayas and Andes. It is one of the most common types of rock garden. An alpine garden tries to imitate the conditions of the plants' place of origin. One example of this is using large stones and gravel beds, rather than the soil that naturally grows there. Though the plants can cope with low temperatures, they dislike standing in damp soil during the winter months. The soil used is typically poor (sandy) but extremely well-drained. One of the main obstacles in developing an alpine garden is the unsuitable conditions which exist in some areas, particularly mild or severe winters and heavy rainfall, such as those present in the United Kingdom and Ireland. This can be avoided by growing the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cultivars
A cultivar is a type of Horticulture, cultivated plant that people have selected for desired phenotypic trait, traits and when Plant propagation, propagated retain those traits. Methods used to propagate cultivars include: division, root and stem cuttings, offsets, grafting, micropropagation, tissue culture, or carefully controlled seed production. Most cultivars arise from purposeful human genetic engineering, manipulation, but some originate from wild plants that have distinctive characteristics. Cultivar names are chosen according to rules of the International Code of Nomenclature for Cultivated Plants (ICNCP), and not all cultivated plants qualify as cultivars. Horticulturists generally believe the word ''cultivar''''Cultivar'' () has two meanings, as explained in ''#Formal definition, Formal definition'': it is a classification category and a taxonomic unit within the category. When referring to a taxon, the word does not apply to an individual plant but to all plants that s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
