Cornus sanguinea 'Midwinter Fire' - This deciduous shrub has oval, mid-green leaves and produces small, creamy-white flowers in May and June. But it's really grown for the brilliant, flame-coloured stems that are revealed when the leaves, which turn orange-yellow in autumn.
Commonly called Basket of Gold, perennial alyssum makes a wonderful wall or rock garden plant. Every spring it develops masses of cheerful yellow flowers that look terrific tucked between rocks and boulders. Alyssum grows 6-12 inches tall and thrives in full sun and well-drained soil. In warmer regions this plant can be short lived, so replant every year or two. You can grow perennial alyssum from seeds or nursery transplants.
