Bougainvillea 'Mary Helen' is a distinctive free-flowering variety known for its remarkable color-changing bracts. The bracts transition from light green and pale yellow to soft pink, often displaying a beautiful blend of yellow, orange, and pink tones on the same branch. Also known as Mary Helen, this green-leaf orange-toned variety is valued for its extremely high flowering frequency, strong adaptability, and captivating color transformation.
Its most notable feature is the chameleon-like color change. The bracts begin as tender green, gradually shift to yellow and orange, and finally mature into pink. Because bracts at different stages of maturity appear at the same time, a single plant can display multiple colors simultaneously, creating a vivid and dynamic visual effect.
