This is one of the flowering plants that surround our condo in the Playa Langosta area of Tamarindo. The center of the flower looks to me a little like popcorn. I think it is a type of heliconia, but I have to admit that I am not very good at identification of different types of plant species. Furthermore, there are more than 10,000 different plant species in Costa Rica that have been documented, but obviously that is too many to be shown in my reference book on Costa Rican plants.
Another excuse for my limited knowledge (besides the fact that my three university degrees included only one class in biology) is that in dividing my time between Costa RIca and the USA, I have lived most of my adult life in Arizona. We primarily have desert plants in Arizona, and of course the plants in Costa Rica are tropical, Thus, much of the vegetation is quite different, which is part of the allure of Costa Rica.
