About

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. This medium-sized evergreen shrub or tree is widely cultivated in gardens.

How to grow it

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.
