Family: Thymelaeaceae

These deliciously fragrant, deciduous and ever-green shrubs, named for the nymph of Greek mythology, are grown throughout the world, except in the tropics. The pretty, waxy, winter or spring flowers are borne in short terminal heads above either narrow or oblong leaves. Some species are upright and shrubby, others low and semi-prostrate. All parts of these plants are highly toxic if eaten.

Cultivation

Daphnes need a well-drained soil, rich in humus, and cool roots. Plant in a semi-shaded position, or in full sun in cool climates. Do not overwater, especially in winter. Being shallow-rooted, daphne is sensitive to root dis­turbance, so keep the root zone well mulched. Propagate from cuttings or from seed. The flower sprays can be cut without harming the plant. Cutting sprigs of flowers for the house is usually all the pruning needed.

Climate

There are species suited to various climatic zones.
