More than four-fifths of the United States filberts are grown in Oregon and nearly all the rest are produced in the State of Washington. Prior to 1933, total filbert production in these two states did not exceed 500 tons, but production has since increased steadily and in 1945 it amounted to 5,320 tons. The value of filbert production in the U. S. in 1945 was about 3 million dollars.[1] As a wild hazel is native of Virginia and as filberts have been profitably grown, especially in Oregon and Washington the question is often raised as to whether hazelnuts or filberts could not be grown commercially in Virginia. It has been suggested that if varieties now available are not successfull in Virginia, perhaps new varieties may be originated by crossing, including inter-specific crosses. +American Species+ AMERICAN HAZEL. As mentioned, one species, _Corylus americana_ Walt., is native to much of Virginia. Its distribution is from the northeastern states and Canada to Saskatchewan and the Dakotas and south to Florida and the Gulf of Mexico. Its adaptation is much wider than that of the beaked hazels (_C. cornuta_ Marsh or _C. roxtrata_ Ait. and the far western _C. californica_) the two other Corylus species native to the United States and Canada. This native _americana_, species appears at least to have value from the point of view of soil conservation, as food for wild life, and for breeding purposes. The American hazel is a large thicket-forming shrub, which sprouts very freely after cutting, and the foliage is generally dense. It is found growing on dry, well-drained sites, in both sun and shade. It, however, seldom bears fruit in the shade. The shrub is relatively hardy, withstanding mid-winter temperatures of -40 deg. to -30 deg.F. and is easily transplanted. The nuts are available in the wild from July through September and occasionally persistent on the plant until December or even February. The nuts average about 250 per pound, with a germination of about 80 percent, producing about 60 usable plants per pound of seed. Three of the best known varieties of _C. americana_ are the Rush from Pennsylvania, the Littlepage from Indiana, and the Winkler (most hardy) from Iowa. [See footnote following.--Ed.][19] Incidentally, Thomas Jefferson in his list of plants native to Virginia, as published in his _Notes on the State of Virginia_, which was written in 1781, and published in 1782, in 1784-1785, and in 1787, lists among other plants the "Hazelnut (_Corylus Avellana_)", which apparently should have been called _Corylus americana_ Walters.
