It is a dense deciduous shrub 2–3 m high and across, with the stems bearing numerous hooked prickles. The foliage has a strong apple-like fragrance. The leaves are pinnate, 5–9 cm long, with 5-9 rounded to oval leaflets with a serrated margin, and numerous glandular hairs. The flowers are 1.8–3 cm diameter, the five petals being pink with a white base, and the numerous stamens yellow; the flowers are produced in clusters of 2-7 together, from late spring to mid summer. The fruit is a globose to oblong red hip 1–2 cm diameter.
The name eglantine is from Middle English eglentyn, from Old French aiglantin (adj.), from aiglent ‘sweetbrier’, from Vulgar Latin *aculentus (with the ending of spinulentus ‘thorny, prickly’), from Latin aculeus ‘prickle’, from acus ‘needle’. Sweet refers to the sweet, apple fragrance of the leaves, while briar ~ brier refers to it being a thorny bush.
Cultivation and uses
In addition to its pink flowers, it is valued for its scent, and the hips that form after the flowers and persist well into the winter. Graham Thomas recommends that it should be planted on the south or west side of the garden so that the fragrance will be brought into the garden on warm, moist winds.
In Tunisia, natural flower water is produced from its flowers.
