Salvia repens is an easy and fast-growing herb with rhizomes that spread to form small clumps of soft, hairy stems about 400 mm tall. Simple or branched, the stems are square ( typical of Salvia) and the aromatic leaves are formed opposite each other along the stem.
The leaves are rough and hairy; the margins toothed and irregular.
The flowers are formed in clusters of 6-8. Formed close to the stem, the clusters of flowers are spaced closer together the nearer to the tip they are. The small, two-lipped flowers (16-24 mm in length) vary in colour from pure white to pale blue, mauve and purple.
It can be very effectively used as a groundcover. Flowering season is quite long.
