[4] [5] R. californica also bears fruit called "rose hips," which contain yellow seeds. [2]
The leaves are evergreen, 2–4 cm (3 ⁄ 4 – 1 + 1 ⁄ 2 in) long and 2–5 mm (1 ⁄ 16 – 3 ⁄ 16 in) broad, green above, and white below, with dense, short, woolly hair.

If the plant is grown in a greenhouse, which blocks ultraviolet light, the petals will be white in color. [1] 'Double Delight' is a medium-tall bushy shrub with large, dark green leaves.
The leaves are pinnately compound, 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 in 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.
