The tiny red hibiscus flowers never open, hence the common name "Sleeping Hibiscus." They are said to resemble Turkish turbans, hence the name "Turk's Cap." The plant's fruit is actually edible, and tastes a little bit like an apple. This is why the Spanish name for the plant is "Manzanilla" or "Mexican Apple." Birds will eat the fruit produced by the pollinated flowers. There is actually a variation of Turk's Cap that has salmon-pink flowers, instead of red.
