Occurring naturally in tropical America, this popular shade tree may reach a height of approximately 24 m, making it unsuitable for small gardens. When mature, it forms a flattopped crown with spreading branches so is ideal in a larger garden where shade is required. Freely flowering, its blooms are masses of pink stamens followed by dark brown seed pods. An intriguing attribute is that its leaves fold up at night or when it rains. There is also a gold-leafed form which is highly attractive.
