Interesting plant, worthy of a little research. There is even debate on how to spell the name. It seems this double flowering variety was found on a single plant and all of the succeeding plants have come from its root cuttings. The single flowering one is the wild variety and may well be the national flower. The double flowering one is unique to Trinidad and Tobago and is the one favored by the plant industry. Like bougainvillea, the color comes from brackets while the small flowers go mostly unnoticed. Very pretty indeed.
