Prinsepia uniflora (common name: rui ren)
Propagation: Seed - best if given 2 months cold stratification[1]. Sow the seed in autumn if possible, otherwise in late winter or early spring in a cold frame in light shade. Germination may be inhibited by light[1]. Prick out the seedlings when they are large enough to handle into individual pots. Grow them on in a greenhouse or cold frame for their first winter and plant them out in late spring or early summer of the following year.
Cuttings of half-ripe wood, July/August in a frame[1].
Cultivation: Succeeds in any moderately fertile well-drained soil in full sun or light shade[2].
The plants produce flowers and fruits better when they are growing in full sun[2].
Hardy to about -20°c[3].
This species is closely allied to P. sinensis[4][5].
Flowers are produced very early in the spring and they are then easily damaged by frosts[4]. The flowers are produced on the previous seasons wood[2]. They are produced on old wood according to another report[6]. Plants only fruit in Britain after long hot summers[2].
Range: E. Asia - N.W. China.
Habitat: Loess plateaux, areas intermediate between woodland and steppe. Sunny slopes, ravines in valleys, base of hills at elevations of 800 - 2200 metres[7].
Edibility: Fruit - raw or cooked[8][9][10]. Juicy[11]. The cherry-like fruit is about 15mm in diameter and contains one large seed[2].
Pollinators: Insects
Soil: Can grow in light, medium, and heavy soils.
Drainage: Prefers well drained soil.
Wind: Tolerates strong winds
Seed Ripens: Mid Summer-Early Fall
