Sage

Sage: Sowing, planting and harvest calendar

Common sage, Salvia officinalis, is an aromatic perennial in the Lamiaceae family, alongside thyme and mint. It is the standard culinary sage. Its leaves have a strong fragrance, with herbal, earthy and lightly peppery notes and noticeable bitterness. The word “sage” covers many species, however. It does not refer to one plant or a handful of varieties with identical characteristics and uses.

Common sage forms a small shrub or subshrub whose base becomes woody with age. Young shoots carry opposite leaves, oval to elongated and usually grey-green. Their surfaces are often velvety, with a visible network of veins. This foliage gives a soft texture both visually and to the touch, while its aroma becomes apparent when crushed. Leaf texture is part of its ornamental appeal as well as its identity.

Foliage is generally evergreen, although its persistence varies with climate and plant condition. The outline becomes more branched and sometimes less compact with age. This is not the growth pattern of an annual herb that disappears after seed formation. Final size varies between selections; some remain more compact than others, even within the same species.

Flowers appear in groups on the stems and have two lips, an arrangement common in the Lamiaceae family. They are often blue to purple and attract bees in particular. Flowering adds another layer of interest to the aromatic foliage. Leaves nevertheless remain the main part valued for common sage’s culinary uses.

Several varieties combine cooking and decoration. ‘Purpurascens’ has purple foliage, ‘Icterina’ yellow-edged leaves and ‘Tricolor’ variegated foliage with different shades. These common sage selections are distinct from clary sage, Salvia sclarea. The latter is another species, often biennial, with large leaves and more imposing flowering stems. Similar names do not establish identical culinary uses for every plant called sage.

In cooking, common sage accompanies meat, poultry, stuffing, potatoes and certain pasta dishes. Fresh or dried leaves contribute a pronounced flavour, including in scented butters and sauces. In a garden, it combines lasting foliage, a velvety texture and summer flowers. The range of colours and sizes gives it a place in herb areas, borders and containers.
