Daphne odora (winter daphne) is a species of flowering plant in the family Thymelaeaceae, native to China, Japan and Korea. It is an evergreen shrub, grown for its very fragrant, fleshy, pale-pink, tubular flowers, each with 4 spreading lobes, and for its glossy foliage. It rarely fruits, producing red berries after flowering.

The Latin specific epithet odora means "fragrant".[1]

It grows best in fertile, slightly acid, peaty, well-drained soils. It grows in full sun or partial shade, and is hardy to −10 °C (14 °F), possibly lower. In Korea, the plant is also poetically called "churihyang" - a thousand mile scent - referring to the fragrance of the foliage. In Japan, the plant is more commonly known as "jinchoge".

Plants are not long lived, senescing within 8 to 10 years.[2] Daphne generally do not react well to root disturbance, and may transplant badly. D. odora is also susceptible to virus infection, which causes leaf mottling.[3]

All parts of the plant are poisonous to humans and a range of domestic animals[4] and some people experience dermatitis from contact with the sap.[5]

Daphne odora is propagated by semi-ripe cuttings in summer.

Cultivars[edit]

  • D. odora f. Rosacea has white and pink flowers.
  • D. odora f. Rubra has dark red-pink flowers with reduced fragrance.
  • D. odora 'Aureomarginata' has yellow edged leaves, and is hardier and more suitable to cultivation than the plain-leaved forms.[3] This cultivar has gained the Royal Horticultural Society's Award of Garden Merit.[6]
