Rose daphne (Daphne cneorum) is a European plant that is evergreen and short, maturing only between 6 and 12 inches. Suitable for USDA zone 4 and warmer areas, the parent species produces brilliant pink April flowers, with the flowers blooming off and on during summer. Cultivar varieties include Alba, which has white flowers, while the flowers and foliage of Eximia are larger compared to those of the parent plant. Other forms of rose daphne are Ruby Glow, named for its dark pink flowering effect, and Variegata, a form with green and white leaves.
The evergreen, leathery foliage of the fragrant daphne (Daphne odora) is dark green and shiny. Growing to 4 feet high, fragrant daphne has the nickname of winter daphne, because it blooms late in winter or just at spring's beginning in USDA zones 7 through 9. This shrub has aromatic rose pink flowers but is not a long-lived variety. Variegata is a cultivar that has yellow edges to its green leaves. Its flowers start out pink, but slowly change to white.
