Salvia microphylla grows to 1 to 1.3 m (3.3 to 4.3 ft) tall and wide, blooming in its first year and growing to full size in its second year. The leaves are ovate shaped, of varying sizes, and smooth or lightly covered with hairs. When crushed, the leaves have a strong fragrance, which has been described as pleasant and mint-like, but also as similar to that of blackcurrants, leading to the use of "blackcurrant sage” as an English name for this species. It sometimes spreads underground, producing dense patches. Along with its cultivars and hybrids, S. microphylla blooms heavily in late spring and again in autumn, with sporadic flowering year-round in mild conditions. The flowers are arranged in whorls, with a wide range of color: magenta, red, pink, and rose.
