This is justifiably one of the most famous vireyas in cultivation. It will flower very freely even when very small and does not rapidly grow into a large plant, especially when confined in a pot
R. viriosum was described in late 2002 and includes all forms of the species previously known as R. lochiae with a straight corolla tube. Plants with a curved tube that were given the name R. notiale in 1996 now revert to the name R. lochiae.
