It cannot be said that the growing of our native varieties is yet commercial, yet advances are made in the way of indicating and naming select varieties which amateurs are planting.
The Butternut Walnut.
The Division of Pomology of the Department of Agriculture gives the following list; but in almost every neighborhood where the Black Walnut grows some good varieties may be found (286).
Large, compressed; shell thin; kernel large; quality good. Original tree now forty inches in diameter. Ohio.
Size medium; form oval; kernel large and plump, and about as good as English walnut in purity of flavor. Missouri.
Small to medium; pyriform; shell thin; kernel entire at the large end of the nut; quality very good. Ohio.
Peanut Walnut. Taylor.
Quite large, quadrangular, pointed; shell thin; kernel large, and coming out in halves; meat white; quality very good. Ohio. Thomas. - Large, oblate, somewhat pointed at base, and still more at apex; shell quite thin; flavor sweet, rich, very good. Pennsylvania.
In Section 288 some notes are given relative to the value of timber and the value of select varieties of the nuts. As with the Black Walnut it is variable in size and thinness of shell of the nuts, and, in some cases, the select varieties have been locally propagated and planted in a small way. Of the flavor and quality of the best varieties Mr. S. B. Heiges, of the Division of Pomology at Washington, says: "In flavor and quality of kernel the butternut is second only to the shellbark hickory and pecan among our native nuts, and is worthy of more attention than it has yet received." This is high praise, as Charles Downing, whose verdict on quality few will dispute says of the shellbark hickory nut: "We confess, to our taste this nut is much superior to the European walnut."
As yet we have no selected commercial varieties.
