SALVIA, a large genus belonging to the natural order Labiatae (q.v.), 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, 5. officinalis (see figure under LABIATAE). S. 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 5. splendens, S. Heerii and 5. 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 From Struburger's Ltkrbuek da Balanik. by permission of Gustav Fischer. Pollination of Salvia Pratensis.

of mellow fibry loam enriched with a little mild thoroughly decom|)osed manure, made sufficiently porous by the addition of sand or Krit. In spring, and during the blooming period, the temperature should be intermediate between that of a stove and greenhouse. There are other very ornamental species of easy growth, increased by cuttings in spring, and succeeding well in ordinary rich loamy soil. Of these S. anguslifolia bears spikes of fine bright-blue flowers in May or June; S. chamaedryoides, a dwarfish subject, has deepblue flowers in August ; 5. fulgens produces scarlet flowers . in August; and 5. involucrata produces fine red flowers during the autumn. 5. patens is a lovely blue free-blooming sort, flowering in August, the colour being unique.
