Cultivation Details

HabitEvergreen Perennial
GrowthMedium

Prefers a light sandy soil in full sun[1]. Plants grown in fertile well-limed soils produce more pigment in the root[2]. This plant was at one time widely cultivated for the red dye obtained from its roots, this dye is now manufactured chemically[3]. However, it is still occasionally cultivated in Europe as a medicinal dye plant. The plant produces many side roots that can travel just under the surface of the soil for some distance before sending up new shoots[4]. This species is closely related to R. peregrina[4].

Propagation

Seed - best sown as soon as it is ripe in a cold frame. Stored seed can be very slow to germinate[3]. Prick out the seedlings when they are large enough to handle and grow them on in light shade in the greenhouse for the first year. Plant them out into their permanent positions in early summer. Division in spring or at any time in the growing season if the divisions are kept well watered until established[3]. Larger divisions can be planted out direct into their permanent positions. We have found it best to pot up the smaller divisions and grow them on in a lightly shaded position in a cold frame, planting them out once they are well established in the summer.
