This tree grows in south Texas and Mexico. It blooms every time it rains and the blooms are fragrant. While the tree is very thorny and not too popular with people, bees love it. It produces a seed pod that is about six to eight inches in length that are very woody. The heartwood is deep maroon but not truly black as the name would imply; however, it is the only exotic wood grown in America. Due to its slow growth and gnarly shape, it is not grown commercially.
Well taken and interesting.
