Opuhi

This too is opuhi. Apparently there are two ginger species that both carry the name opuhi. The one I presented in my earlier entry is  Zingiber zerumbet, but the more plumelike Alpinia purpurata seems to go by this name too. The more than 230 ginger species are listed in the Alpinia genus, so apparently not all gingers have the Latin name of Zingiber. Alpinia purpurata which is shown in the picture above is also called Red Ginger, Ostrich Plume, Jungle Queen and Pink Cone Ginger. Indeed I have seen pink flowers as wel as red ones. The pink ones, however, seem to be sturdier than the red ones. Tahitian women avoid planting them together, because the pink ones would soon take up all the space and they would lose the red ones.

The BPAL scent Opuhi carries "ginger blossom" as wel as "vanilla orchid" and it appears that  Vanilla too has more than one species. The one we are most used to is Vanilla planifolia, which originates in Mexico but which has spread more widely since it was discovered that the flowers could be hand-pollinated. Bourbon vanilla is from the same plant, but grown on Indian Ocean Islands such as Madagascar, the Comoros, and Réunion, formerly called Île Bourbon. Tahitian Vanilla however is a different species, Vanilla tahitiensis. It is said to have an unique aroma which is more floral and fruity than the planifolia vanilla. (vanilla types)
