Roscoea purpurea f. rubra syn. 'Red Gurkha'

Fantastic Roscoea only discovered in the 1980's in Nepal and still scarce as hen's teeth in the nursery trade and always commanding very high prices. Why is this so good? It represents a color break in Roscoea with large red flowers which resemble some exotic orchid except this is easier to grow! It's a show-off plant for sure. In the trade as 'Red Gurkha' but recent nomenclature based on determining that this represents a naturally occurring variation of the species in stable wild populations in Nepal eliminates the perfect clonal name which everyone is still going to use.
