In 1997, my brother and I toured Costa Rica. We traveled to the highlands of Central Costa Rica, the Northwestern border near Nicaragua, and the beaches of Quepos. Frequently, on our travels, we saw young boys waving stalks filled with white blossoms at us. It was the same motions that I used when selling sweet corn from my front yard as a young boy. It was obvious that they were trying to sell something. Finally, we asked the caretakers at one of our guesthouses to help us understand what was going on. He explained that the boys were selling yucca to be eaten in salads.
