The herbaceous weed produces stems that are thin, hairless and often purple in colour, up to 30 cm long. Leaves are arranged alternately along the stem. The leaves are ovate to lanceolate, usually 1–2 cm long, green in colour with serrated margins. The underside of the leaves are often purple in colour. The weed has long white rhizomes and it produces distinct flowers with 5 petals that are mostly white (tinged with pink or purple). Flowers are seen between spring through to autumn. The weed also produces small fruit that is egg-shaped and fleshy. The weed is frost hardy. Some gardeners use this weed as a "ground cover".
