Template:Short description Template:Other uses of Template:Automatic taxobox
Pieris (Template:IPAc-en or Template:IPAc-en<ref name=OXDI>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>)<ref>Template:OED</ref> is a genus of seven species of shrubs in the flowering plant family Ericaceae, native to mountain regions of eastern and southern Asia, eastern North America and Cuba. Known commonly in North America as andromedas or fetterbushes, they are broad-leaved evergreen shrubs growing to Template:Convert tall and Template:Convert wide. The leaves are spirally arranged, often appearing to be in whorls at the end of each shoot with bare stretches of shoot below; they are lanceolate-ovate, Template:Convert long and Template:Convert broad, leathery textured, and with an entire or serrated margin. The young leaves in spring are typically brightly coloured. The flowers, which may have a very appealing honey scent, are bell-shaped, Template:Convert long, white or pink, and arranged in racemes Template:Convert long. The fruit is a woody capsule which splits into five sections to release the numerous small seeds.
Pieris species are used as food plants by the larvae of some Lepidoptera species including the engrailed.
The genus name derives from Pieria, a place in Greece, according to Greek mythology the home of the Muses.<ref name=OXDI />

CultivationEdit
They are commonly grown as ornamental plants, valued for year-round interest due to bright red new growth in early spring, chains of small, white flowers in mid-spring, and buds that remain on the plant through the winter. Numerous cultivars have been selected for different spring foliage colour. They grow best in a shady spot, sheltered from drying, winter winds. They prefer acidic soil, and should be mulched once per year, using a two-inch covering of either peat or composted pine needles. The flowers give the plant one of its alternative names, 'Lily of the valley shrub' (though Pieris is not closely related to Convallaria).
