The illustrated growing guide
Pieris (Andromeda)
Pieris japonica
Family Ericaceae
Est. zones 5-8

A four-season evergreen for the acid, shady bed: dangling white or pink bell chains in early spring, brilliant red new growth, and next year's flower buds hanging decoratively all winter. Same needs as azaleas and rhododendrons (acid, moist, part shade), and the same clay-and-sun intolerance. Lace bugs are the pest to watch. Toxic like the rest of the heath family.
