Growth

It is a low-growing, spreading very quickly evergreen shrub 20–40 cm tall. The leaves are opposite or in whorls, ovate, 4–7 cm long and 1.5–4 cm broad, with a sharply serrated margin and an acute apex. The flowers are 4–10 mm diameter, with five (rarely six) white to pale pink petals; they are produced in racemes in late spring. The fruit is a drupe 5–6 mm diameter, red maturing dark purple-black in early winter.[2][3]

Uses

A number of cultivars have been selected for growing as ornamental plants, including 'Hakuokan' and 'Ito Fukurin' with variegated leaves, 'Hinotsukasa', with pale cream-coloured leaves, and 'Matsu Shima' with pink stems and variegated leaves.[3]

Medicinal uses

It is used as a medicinal plant in traditional Chinese medicine, where it is called zǐjīn niú (Chinese: 紫金牛),[2] or aidicha (矮地茶) and is considered one of the 50 Fundamental Herbs.[4]

Large doses of the plant as medicine can be toxic to the kidneys.[5]

Weed problems

It has escaped from cultivation and established itself in the wild in the United States, in Gainesville, Florida.[6]
