Containing about 900 species of annuals, perennials, and softwooded evergreen shrubs, this genus is the largest in the mint family. They are found in temperate and sub-tropical regions throughout the world, with the exception of Australasia, and grow in a wide range of habitats, from coastal to alpine. A number of Salvia species are used for culinary and medicinal purposes, and the genus name is derived from the Latin salvare, meaning to heal or save. Most species are hairy to some extent and many have foliage that is aromatic when crushed or rubbed. The flowers are tubular with the petals split into 2 lips, which may be straight or flaring. The flowers vary greatly in size, and the color range move through shades of blue to purple, and pink to red, as well as white and some yellows.
CULTIVATION
Most are best grown in full sun and all require a well-drained situation; generally, the shrubby plants dislike heavy wet soils. Propagation of most shrubby species is very easy from soft-wood cuttings taken throughout the growing season. Seed of all species is sown in spring.
Top Tip
While many Salvia or sage plants are tolerant of considerable dryness, most benefit from an occassional deep watering.
