SALVIA Sage, salvia

This genus of the mint family contains hundreds of perennial and annual species grown for flowers, foliage, and herbal uses. Tubular flowers are carried on upright spikes over bushy, smooth to densely hairy, and often fragrant foliage. Red-flowered plants, such as scarlet sage (Salvia splendens), are often annuals or tender perennials, while most perennial species, including garden sage (S. officinalis), flower in shades of blue or purple. Silver sage (S. argentea) bears unimpressive white flowers that pale next to the large, crinkly, woolly leaves. Plants grow from 1 to 4 feet tall with similar spread.

Grow sages in full sun or light shade in average, well-drained soil. Some species tolerate heat and drought, but most flower more freely if kept evenly watered. Very hot weather may interrupt blooming, even if plants are well tended. A summer mulch helps retain moisture in the soil and keeps roots cool. In areas where temperatures fall below 0°F, protect perennial species by applying a winter mulch after the soil freezes. Remove faded flower spikes to encourage branching. Few pests or diseases cause significant damage to sages.
