How to Grow
We have very little information on this species and do not know if it will be hardy in Britain, though judging by its native range it should succeed outdoors in many parts of the country. According to one report this species is no more than a synonym of R. pensylvanicus. The following notes are based on the general needs of the genus. Easily grown in a good well-drained loamy soil in sun or semi-shade. Plants in this genus are notably susceptible to honey fungus.
Propagation: Seed requires stratification and is best sown in early autumn in a cold frame. Stored seed needs one month of stratification at around 3°c and should be sown as early in the year as possible. Prick out seedlings once large enough to handle and grow on in a cold frame before planting into permanent positions in late spring of the following year. Cuttings of half-ripe wood can be taken in July or August in a frame. Tip layer in July and plant out in autumn. Division can be done in early spring or just before leaf-fall in autumn.
