This is very much a lowland species although it still usually occurs on hills, and it requires more heat than most Vireyas to do well. It was confused with R. praetervisum but the leaves of this species are much more revolute, the flowers purplish pink and hanging rather than semi-erect. Royal Horticultural Society (1997)
