Comments: A fast growing tree suitable for screens in wet areas. This is not a native tree, but has escaped cultivation. The mature fruit is interesting in that it is a small, nut-like cone that presists over winter and is a wildlife food. Well adapted for plantings adjacent to ponds, lakes and other bodies of water. Has several features throughout the year from spring through the winter when plants are deciduous.
