What is a coconut flower / blossom?

The Coconut tree/palm is one of the oldest flowering tree in the world, the coconut flowers blossom only after 6 to 10 years depending on the species.

The flowers develop inside a large green bud which is called 'The Spathe' which keep both male and female flowers. (A 'Spathe' is a large leaf that enclose the flower to keep certain plants such as palms,  arums, and dayflowers.)

The bud splits open as the flowers grow, the several branches inside have hundreds of tiny male flowers which look like lilies and few female flowers which look like small coconuts.

Flowering occurs continuously and with the help of the insects and wind the male flowers pollinate the female flowers. Once the female flowers are pollinated, they become mature coconuts after a period of 10 months.

Coconut sap is extracted from the coconut flowers to produce toddy (an alcoholic drink) and coconut nectar.
