A Japanese form of this subtropical looking small tree from the Far East. This has grown here for years, even through the intense cold of 2010 and is completely hardy once established. Forms a very distinctive wide spreading low crown up to about 7m tall, with long pinnate foliage, very large compared to other species. Large flattened heads of white flowers in autumn as the leaves turn to shades of yellow. The trunk is armed with persistent small woody spines, the shape of a wizard's hat.
