Salvia is the largest genus of plants in the mint family, Lamiaceae, with approximately 900 species of shrubs, herbaceous perennials, and annuals.[2] It is one of several genera commonly referred to as sage. When used without modifiers, sage generally refers to Salvia officinalis ("common sage"); however, it is used with modifiers to refer to any member of the genus. The ornamental species are commonly referred to by their scientific name Salvia.
The genus is distributed throughout the Old World and the Americas, with the center of diversity and origin appearing to be Central and Southwestern Asia,[3] while nearly 500 species are native to Mexico and Central and South America.[4]

Salvia species include annual, biennial, or perennial herbs, along with woody subshrubs. The stems are typically angled like other members in Lamiaceae. The leaves are commonly entire, but sometimes are toothed, or pinnately divided. The flowering stems bear small bracts, dissimilar to the basal leaves, in some species they are ornamental and showy.
The flowers are produced in racemes, or panicles, and generally produce a showy display with flower colors ranging from blue to red, with white and yellow less common. The calyx is normally tubular or bell shaped, without bearded throats, and divided into two parts or lips, the upper lip entire or three-toothed, the lower two-cleft. The corollas are often claw shaped and are two-lipped. The upper lip is usually entire or three-toothed. The lower lip typically has two lobes. The stamens are reduced to two short structures with anthers two-celled, the upper cell fertile, and the lower imperfect. The flower styles are two-cleft. The fruits are smooth ovoid or oblong nutlets and in many species they have a mucilaginous coating.[5]
Many salvias have trichomes (hairs) growing on the leaves, stems, and flowers, which help to reduce water loss in some species. Sometimes the hairs are glandular and secrete volatile oils that typically give a distinct aroma to the plant. When the hairs are rubbed or brushed, some of the oil-bearing cells are ruptured, releasing the oil. This often results in the plant being unattractive to grazing animals and some insects.[6]
George Bentham was first to give a full monographic account of the genus in 1832-1836, and based his classifications on staminal morphology.[7] The defining characteristic of the genus Salvia is the unusual pollination mechanism, which consists of two stamens (instead of the typical four found in other members of the tribe Mentheae) and the way the two stamens are connected to form a lever. When a pollinator enters the flower for nectar, the lever activates causing the stamens to move and the pollen to be deposited on the pollinator. When the pollinator withdraws from the flower, the lever returns the stamens to their original position. As the pollinator enters another flower of the same species, the stigma is placed in a general location that corresponds to where the pollen was deposited on the pollinator's body. The lever of most Salvia species is not specialized for a single pollinator, but generic and selected to be easily released by many bird and bee pollinators of varying shapes and sizes.[8] It is believed that this is a key factor in the speciation of this large group of diverse plants.[9] Because this structure is nearly exclusive to Salvia, the genus was thought to be monophyletic. However, it now appears that somewhat different versions of this lever mechanism have evolved in the tribe Mentheae, and at least three different times within Salvia, making the genus clearly non-monophyletic.[10][11]
The classification of different Salvia species has been confused. Many species are similar to each other, and many species have varieties that have been given different specific names. Salvia officinalis, for example, has been described and named under six other specific names at various times. At one time there were over 2000 named Salvia species. That number has been reduced in recent years to 700-900 distinct species and subspecies, depending on the source.[12][13]
Many species are used as herbs, as ornamental plants (usually for flower interest), and sometimes for their ornamental and aromatic foliage. A selection of the most important species is below.
Salvia species are used as food plants by the larvae of some Lepidoptera (butterfly and moth) species including the bucculatricid leaf-miner Bucculatrix taeniola which feeds exclusively on the genus and the Coleophora case-bearers C. aegyptiacae, C. salviella (both feed exclusively on S. aegyptiaca), C. ornatipennella and C. virgatella (both recorded on S. pratensis).
Both botanic and common names are derived from the Latin salvere ("to save"), referring to the long-believed healing properties of salvia. The derivation of the common English name is through the old French form 'sauge', then to the old English 'sawge', and eventually to the modern day 'sage'.[21] Pliny the Elder was the first known to use the Latin name salvia.[22]
SALVIA, a large genus belonging to the natural order Labiatae, containing about 500 species in the temperate and warmer regions of both hemispheres. The name is derived from the Lat. salvo, from the healing properties of sage, S. officinalis (see figure under Labiatae). verbenaea, Clary, is a native of Britain found in dry pastures and waste places.
Some of the Salvias are among the most showy of the soft-wooded winter-flowering plants, the blossoms being of a bright glowing scarlet. The three most useful species are S. splendens, S. Heerii and S. gesneriflora, the first beginning to flower early in the autumn and lasting till Christmas, while the others follow immediately in succession, and continue in full beauty till April. Young plants should be propagated annually about February, and after nursing through the spring should be grown outdoors in a fully exposed situation, where they can be plunged in some non-conducting material, such as half-decomposed leaves. The young shoots should be stopped to secure bushy plants, but not later than the middle of August. The most suitable compost for them is a mixture 4, The staminal apparatus at rest, with connective enclosed within the upper lip.

Of these S. angustifolia bears spikes of fine bright-blue flowers in May or June; S. chamaedryoides, a dwarfish subject, has deepblue flowers in August; S. fulgens produces scarlet flowers in August; and S. involucrata produces fine red flowers during the autumn. S. patens is a lovely blue free-blooming sort, flowering in August, the colour being unique.

Salvia is a genus in the mint family, Lamiaceae. It is one of three genera commonly referred to as Sage. Sage generally means common sage (Salvia officinalis). This genus includes shrubs, herbaceous perennials, and annuals. Different species of sage are grown as herbs and as ornamental plants. The ornamental species are commonly referred to by their scientific name Salvia.
