Pieris

General description: evergreen shrub. 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.

Common name: Pieris

Family: Ericaceae

Height: 1.5  m.

Aspect: partial shade; sheltered

Soil requirements: acid

Why we use in horticulture: 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.

Euonymus

General description: Euonymus is a genus of flowering plants in the staff vine family, Celastraceae. The flowers occur in small groups, inconspicuous and of green or yellow shades. The leaves are opposite (rarely alternate) and simple ovoid, typically 2–15 cm long, and usually with a finely serrated margin.
The fruit is a pink-red four- or five-valved pod-like berry, which splits open to reveal the fleshy-coated orange seeds. The seeds are eaten by frugivorous birds, which digest the fleshy seed coat and disperse the seeds in their droppings

Common name: Euonymus;  Spindle;  Spindle Tree

Family: Celastraceae

Height: 2.5  m.

Aspect: sunny or partial shade

Soil requirements:

Why we use in horticulture: for the attractive foliage (red in autumn as in E. alatus; many species have variegated leaves, as in E. fortunei) and berries

Notes: the wood of some species was traditionally used for the making of spindles for spinning wool; this use is the origin of the English name of the shrubs.
