The shape of Plumeria flowers aids in pollination by providing easy access to pollinators. Plumeria flowers have a funnel-shaped structure with a wide opening, allowing pollinators to land and move freely inside the flower while collecting nectar and pollen. The reproductive organs (stamen and pistil) are located within the flower and positioned in a way that ensures effective pollen transfer during pollinator visits. The flower’s shape, combined with its fragrance and nectar rewards, make Plumeria flowers attractive and efficient in promoting pollination by encouraging repeat visits from pollinators.
