The Daphne shrub is a genus of 75 to 90 species of shrubs. They are noted for their scented flowers and brightly colored berries. Flowering takes place in late winter to early spring. All parts of the Daphne are poisonous, especially the bright berries. Two of the Burkwood cultivars (Carol Mackie and Briggs Moonlight) are more common and could be excellent choices for your yard.Carol Mackie plants are compact, rounded shrubs that mature to about 3 feet tall, with a slightly greater spread. They bear fragrant, white to light pink, tubular flowers in clusters and their blooming time is generally in early May. The flowers are followed by small red berries (drupes) if pollination occurs. Perhaps the outstanding feature of Carol Mackie plants is their variegated foliage.Despite being classified as deciduous, some refer to Carol Mackie as "semi-evergreen." The Daphne shrubs in a zone 5 garden will usually keep their leaves throughout the winter; the leaves do not become unattractive until late winter.
