This is another one of those “international migrants” in Costa Rica that grows well here but is native in this case to Brazil, Surinam, & Venezuela. At first glance I though it was a Red Ginger, but on a closer look, there are several differences! It is just one more species I’ve added to my Under Construction CR Flowers by Species with only this photo in the Brazilian Red-cloak gallery now. You can read about and see where others have seen this flower in Costa Rica on iNaturalistCR by clicking “View All” under TOTAL OBSERVATIONS where there is a map showing where. Or read more about them on Wikipedia (en español) or shorter one in English.
¡Pura Vida!
