Abstract

The genus Daphne L. (Thymelaeceae family) contains approximately 70 species distributed across Europe and temperate and subtropical Asia, with a few representatives in North Africa. All species can be classified as shrubs, and vary in stature between the prostrate D. jasminea (eastern Mediterranean) and the upright D. bholua (eastern Himalayas), which can grow to over 3 m. Daphne plants are grown for their ornamental value in Europe, New Zealand (Christie and Brascamp 1989) and the USA (Gaschk 1989), where they are noted particularly for the fragrance of their flowers, often borne in early spring when few other shrubs are in bloom, and for their generally dwarf growth habit. However, their commercial availability is limited due to their slow growth, and the protracted development of a saleable plant of good form in the nursery. Where they can be readily propagated by seed (D. mezereum, D. laureola and D. pontica) or by cuttings (D. x burkwoodii and D. odora clones and D. cneorum forms) plants are more readily available (Brickell and Mathew 1976). In general, most species are currently underexploited.
