These are large vigorous seedlings grown from seed collected by Peter Cox and myself on the S Yunnan/N Vietnam border at around 9,000 ft. in 1995. It bears a remarkable resemblance to the well-known species R. hemsleyanum (which is only known from Emei Shan in Sichuan Province 450 miles to the north of this area!) with the same auriculate leaf base and wavy margins. However, the leaves are much narrower and the habit is more open. David Chamberlain has seen this same taxon in N Vietnam and feels that we have finally found the long lost and little known R. serotinum. Plants under this name have floated around for years but appear to be mostly forms or hybrids of diaprepes. The new growth emerges quite late in the spring (even under cover) on these plants and so should miss the spring frosts which can be so damaging to other species from such southern latitudes.Beautiful blue-green foliage and rapid growth on this exciting new introduction.
1977/754Windsor(0).Close ally of R. decorum notable for very late fragrant white flowers lingering into September on a thinly vertical shrub.
1996sd562SEH#242:RSBG (+5 to 0?\R1\8).A new introduction from S Yunnan.The quite large, white and fragrant flowers appear in mid-summer.This vigorous species has foliage similar to that of R. hemsleyanum but with a more upright and narrow growth habit and much larger flowers.These are grown from my collection of seed at 9,000 ft. near the N Vietnam border.
