hortiphoto...many thanks for your suggestion. However having searched www I am not sure that we have a match. The length of the petiole , the leaf veins, the structure of the flower just don't look a perfect match But maybe I am not correct? costus lasius - Google Search:
I hope I'm not misremembering, but I think I saw Costus lasius at the US Botanic Garden in Washington, DC today and it had slightly but noticeably fuzzy leaves top and bottom, and slimmer leaves. I convinced myself that I had no reason to photograph it.
wcutler...next time you will take pics! Thanks for help. Lila...that looks perfect for the leaves. My flower is not yet fully open. Many thanks....much appreciated.
