Salvia

Salvia is the largest genus in the mint family (Lamiaceae), with hundreds of species ranging from the culinary herb common sage (Salvia officinalis) to ornamental border sages and dramatic flowering shrubs. The name comes from the Latin salvere, “to heal,” reflecting the herb's long medicinal history.

Salvias share aromatic foliage and characteristic two-lipped tubular flowers carried on spikes, in colors from the scarlet of bedding salvia (Salvia splendens) to the deep blues and purples of perennial border sages. They are tough, mostly drought-tolerant plants that flower over a long season.

This profile centers on culinary sage but reflects the genus's enormous ornamental and herbal range.

Salvias share the aromatic foliage and hooded flowers of the mint family.

• Flowers: Tubular, two-lipped blooms arranged in whorls along upright spikes; colors include red, blue, purple, pink, and white
• Leaves: Opposite, often gray-green, soft or textured, and strongly aromatic when crushed
• Stems: Square in cross-section (typical of the mint family)
• Habit: Ranges from low herbaceous perennials and bedding annuals to woody subshrubs
• Size: From compact 1-ft mounds to shrubby sages over 4 ft tall

Most salvias are sun-loving and drought-tolerant once established.

• Light: Full sun for best flowering and flavor
• Water: Let soil dry between waterings; most salvias are drought-tolerant and dislike wet feet
• Soil: Well-drained soil is essential; lean to average fertility suits them
• Temperature: Hardiness varies widely by species; culinary sage is hardy in USDA zones 4-8
• Feeding: Minimal; over-feeding reduces flowering and aroma
• Propagation: Cuttings root easily; many species grow from seed, and clumps can be divided

Trim woody sages lightly in spring to keep them bushy, and deadhead ornamental salvias to prolong bloom.

Salvias occur across the Americas, Europe, Asia, and Africa, with major centers of diversity in Central and South America and the Mediterranean. Culinary sage (Salvia officinalis) is native to the Mediterranean region, growing on dry, sunny, rocky hillsides.

The genus's wide range means salvias are adapted to many habitats, from arid scrub to montane grassland. Ornamental and culinary salvias are now grown in temperate and warm gardens worldwide.

Salvia spans culinary, ornamental, and medicinal uses. Common sage is a classic culinary herb, its aromatic leaves used in stuffings, sauces, and meat dishes.

Ornamental salvias are prized garden plants and outstanding pollinator magnets, with their tubular flowers especially attractive to bees and hummingbirds. Sage has a long herbal and traditional medicine history (as an antiseptic and digestive aid), and some species are grown for essential oils. Note that a few salvias, such as Salvia divinorum, are psychoactive and unrelated to garden or kitchen sage.
