Pieris japonica

provided by wikipedia EN

Pieris japonica, the Japanese andromeda or Japanese pieris, is a species of flowering plant in the heath family Ericaceae. It is native to eastern China, Taiwan, and Japan, where it grows in mountain thickets.[2] This medium-sized evergreen shrub or tree is widely cultivated in gardens.

Description

Pieris japonica grows to 1–4 metres or 3.3–13.1 feet tall, occasionally up to 10 metres, with alternate, simple leaves on brittle stems. The leaves open bronze or red in some cultivars, turning green. The trusses of small urn-shaped flowers are white or pink, appearing early in spring, and providing a decorative effect against the young red leaves. The flowers usually last two or three weeks.

The plant is poisonous if consumed.[3] The toxicity is a result of the grayanotoxins contained by the flowers and leaves. If flowers and leaves are ingested by humans, symptoms may include salivation, headaches, vomiting, cardiac failure, and death.[4] Cattle, goats, horses, dogs, and cats may suffer similar symptoms after ingesting the leaves or flowers of this plant.[5]

The name "andromeda" originated from an earlier genus name for the plant.

Cultivation

Pieris japonica is a popular temperate garden plant, producing colour in early spring. A calcifuge, it requires acid pH soil, typically in a partially shaded setting such as dappled woodland. It associates well with camellias, rhododendrons, and other lime-hating plants.
