Description

Rosa rubiginosa (sweet briar,sweetbriar rose,sweet brier or eglantine;syn. R. eglanteria) is a species of rosenative to Europe and western Asia.

The rose hip, also known as rose haw or rose hep, is the fruit of the rose plant, that typically is red-to-orange, but ranges from dark purple to black in some species. Rose hips begin to form after successful pollination of flowers in spring or early summer, and ripen in late summer through autumn.

It is a dense deciduous shrub 2–3m high and across, with the stems bearing numerous hooked prickles. The foliage has a strong apple-like fragrance. The leaves are pinnate, 5–9cm long, with 5–9 rounded to oval leaflets with a serrated margin, and numerous glandular hairs. The flowers are 1.8–3cm 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 1–2cm diameter.
