Chimonanthus–commonly called wintersweet–is a mid-size deciduous shrub that blooms in late winter and early spring. Its small sulfur yellow flowers are very fragrant and are borne on bare branches. Lance-shaped, glossy, mid-green leaves emerge after the plant flowers.

Chimonanthus can be grown as a late winter specimen plant; set it in front of evergreens for the best display of color. It can be grown in a shrub border or against a sunny wall. Plant Chimonanthus along a walk where the fragrant flowers can be enjoyed.

Chimonanthus grows to 12 feet (4m) tall and 10 feet (3m) wide. It can be planted in full sun or partial shade. It can tolerate wet soil but is best grown in a well-drained loamy soil.
