Red Mulberry Revisited
Looking at the little map in my field identification guide, Red Mulberry (Morus rubra L.) grows in the Eastern U.S. right on down to the tip of Florida, as far west as Texas, and throughout most of the mid-western states. In rich moist soils, it can grow 50' - 70' tall and up to 2' - 3' in diameter.
There are about 1,000 trees, shrubs, and herbs in the Mulberry family and, with the exception of the two herbs Hop (Humulus spp.) and Hemp (Cannabis spp.), all produce a milky sap, or latex. The leaves are broadly ovate 3" - 5" long by 2" - 3" wide. Often the leaves have two and three lobes: the two-lobe patterns looking just like winter mittens. They produce a juicy edible fruit about an inch or so long which is red at first and deep purple when mature.
In lumber form, the sapwood is narrow and yellowish; the heartwood is orange-yellow to golden brown turning "russet" brown upon extended exposure to light. It has distinct rings, is ring porous with abrupt transition from the large early wood pores to the small latewood pores.
The wood is heavy and hard with a specific gravity of .59 when green. Generally, a wood is considered hard and heavy if its specific gravity is .50 or more. It has light yellow rays easily visible to the naked eye and can be sawn for a nice fleck figure.
In his books, Dr. Hoadley ranks Mulberry very high in rot resistance. Consequently, it has been used for caskets, fences, cooperage and farm implements. However, it is also nice for furniture and interior finish work.
