This is the only blue-fruited haw in the world. This unique character alone must commend it to planters. The stout, curving thorns, the lustrous foliage, the abundant flowers, and the large blue fruit-all make this one of the best ornamental species. On the wet prairies of western Louisiana, this tree forms dense thickets which are quite the dominating feature of the woods.
