Salvia Blancoana
''Salvia blancoana'' is a prostrate perennial that is native to Spain and northwest Africa. It has narrow blue-green leaves and pale violet-blue flowers. Due to its being highly variable in the wild, and because of similarities to ''Salvia candelabrum ''Salvia candelabrum'' is a species of flowering plant in the family Lamiaceae, native to Spain. It is a woody-based perennial growing to , with woolly grey-green leaves that resemble those of the common sage, '' S. officinalis'', and emit a sim ...'' and ''Salvia officinalis'' subsp. ''lavandulifolia'' (syn. ''S. lavandulifolia''), it has often been confused with those two. Current opinion gives ''S. blancoana'' distinct species status, even while some botanists consider it a subspecies of its two close relatives. It differs from ''S. officinalis'' subsp. ''lavandulifolia'' and ''S. candelabrum'' in being prostrate, as opposed to merely low-growing. It also has whorls of 2–6, compared to 6–9 in ''S. offi ...

Philip Barker Webb
Philip Barker Webb (10 July 1793 – 31 August 1854) was an English botanist. Life Webb was born to a wealthy, aristocratic family; his father was the lord of the manors of Witley and Milford, Surrey, Milford, in Surrey, England. Webb was educated at Harrow School and Christ Church, Oxford. He collected plants in Italy, Spain, and Portugal, and was the first person to collect in the Tetuan Mountains of Morocco. En route to Brazil he made what was intended to be a brief visit to the Canary Islands, but he stayed for a considerable time, returning after his Brazil expedition. The results can be seen in the nine-volume ''Natural History of the Canary Islands, Histoire Naturelle des Iles Canaries'' (''Natural History of the Canary Islands''), which he co-authored with Sabin Berthelot. In company with Berthelot, who had lived on the islands for some time, Webb collected specimens on the islands between 1828 and 1830. The text of ''Histoire Naturelle des Iles Canaries'' took 20&nb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
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] |
Salvia Candelabrum
''Salvia candelabrum'' is a species of flowering plant in the family Lamiaceae, native to Spain. It is a woody-based perennial growing to , with woolly grey-green leaves that resemble those of the common sage, '' S. officinalis'', and emit a similar scent when crushed. In summer it bears violet-blue flowers on branching stems held high above the foliage. Diterpenes have been isolated from its green tissues. From the aerial parts of ''Salvia candelabrum'' have been isolated β-sitosterol, nepeticin (lup-20(29)-ene-3j,lla-diol), candelabrone (11,12,14-trihydroxy-8,11,13-abietatriene-3,7-dione), the rearranged abietane diterpenoids candesalvone A (11,12,14-trihydroxy-19(4→3)-abeo-3,8,11,13-abietatetraen-7-one) and candesalvone B (11,12,14-trihydroxy-7-oxo-3,4-seco-4(18),8,11,13-abietatetraen-3-oic acid), and large amounts of ursolic and oleanolic acids. The root bark afforded 7α-acetoxyroyleanone, 12-O-methypisiferic acid and sugol. This plant has ornamental value in the gar ...

Salvia Officinalis Subsp
''Salvia'' () is the largest genus of plants in the sage family Lamiaceae, with nearly 1000 species of shrubs, herbaceous perennials, and annuals. Within the Lamiaceae, ''Salvia'' is part of the tribe Mentheae within the subfamily Nepetoideae. One of several genera commonly referred to as sage, it includes two widely used herbs, ''Salvia officinalis'' ( common sage, or just "sage") and ''Salvia rosmarinus'' (rosemary, formerly ''Rosmarinus officinalis''). The genus is distributed throughout the Old World and the Americas (over 900 total species), with three distinct regions of diversity: Central America and South America (approximately 600 species); Central Asia and the Mediterranean (250 species); Eastern Asia (90 species). Etymology The name ''Salvia'' derives from Latin (sage), from (safe, secure, healthy), an adjective related to (health, well-being, prosperity or salvation), and (to feel healthy, to heal). Pliny the Elder was the first author known to describe a p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
