Pieris is a genus of seven species of shrubs in the family Ericaceae, native to mountain regions of eastern and southern Asia, eastern North America and Cuba, known commonly as andromedas or fetterbushes. 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.
Description[edit | edit source]
They are broad-leaved evergreen shrubs growing to 1-6 m tall. 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, 2-10 cm long and 1-3.5 cm broad, leathery textured, and with an entire or serrated margin. The young leaves in spring are typically brightly coloured. The flowers are bell-shaped, 5-15 mm long, white or pink, and arranged in racemes 5-12 cm long. The fruit is a woody capsule which splits into five sections to release the numerous small seeds.
