History of the Filbert.—It is claimed that the filbert was first known to the Romans as Nux Pontica, because introduced from Pontus; but it must have become naturalized throughout southern Europe in very early times. But the Italian name of Avellana appears to have been applied to the wild hazel of Britain, long before Linnæus adopted it as the specific name of the indigenous species. John Evelyn, one of the most careful and learned of English arboriculturists of his time, in referring to these nuts, in his "Sylva," 1664, says: "I do not confound the filbert Pontic, distinguished by its beard, with our foresters or bald hazelnuts, which, doubtless, we had from abroad, bearing the names of Avelan or Avelin, as I find in some ancient records and deeds in my custody, where my ancestors' names were written Avelan, alias Evelin."
The filbert has been celebrated in prose and poetry from ancient times, as we may infer from a remark of Virgil, who says that it has been more honored "than the vine, the myrtle, or even the bay itself" (Eclogue vii).
The supposed occult power of a forked twig of the hazel as a divining-rod (virgula divinatoria) for finding hidden treasures, veins of metals, subterranean streams of water, and even pointing out criminals, is, of course, purely mythical, although so solemnly attested by many learned men in the past; and I would not consider this myth worthy of a notice here were it not for the fact that it was early imported into this country, and is still firmly believed by many persons among our rural population. It is true that the supposed attributes of the European hazel have been transferred to different plants in this country, mainly to the peach and our indigenous witch-hazel (Hamamelis Virginiana), but the myth still lives, a legitimate descendant of an Old World nut tree.
There is little to be said in regard to the history of the filbert and hazelnut in this country, but it is quite likely that both of the European species, and many varieties, were brought here and planted by the early settlers in the Eastern States, and bushes of the same could have been seen in many gardens a hundred years ago; but I have been unable to find any account of extensive plantings of these nuts, although nurserymen, all along, have been offering choice varieties to their customers. In the main, our pomologists have either remained silent in regard to these nuts, or, at most, referred to them very briefly in their published works.
William Prince, of Flushing, N. Y., in a "Short Treatise on Horticulture," published in 1828, refers to the filbert as follows:
"This shrub or, in some cases, tree, accommodates itself to every exposition, and to every variety of soil, but prefers a moist loam on a sandy bottom, with a northern exposure. It is easily multiplied by seeds, layers or inoculation. In fact, these nuts, which are vended in large quantities in our markets, grow as well in our climate as the common hazelnut, and produce very abundantly. Such being the case, it is hoped, ere long, sufficient will be produced from our soil to supersede the necessity of importation, as plantations of this tree would amply remunerate the possessor; or if planted as a hedge, would be found to be very productive. A single bush of the Spanish filbert in my garden has produced a half-bushel annually."
Mr. Prince then names a few of the best varieties, which are about the same as those recommended at the present time, and he was, no doubt, honest in recommending filbert culture to his countrymen, for his own limited experience proved that the trees would grow here and fruit abundantly.
A. J. Downing, in the first edition of his "Fruits and Fruit Trees of America," 1845, says: "The Spanish filbert, common in many of our gardens, is a worthless, nearly barren variety; but we have found the better English sorts productive and excellent in this climate (Newburg, N. Y.), and at least a few plants of these should have a place in all our gardens." If a few plants will succeed in a garden, then we might reasonably suppose that the number might be safely increased, and this was the idea of Mr. Prince, and many other writers on the subject since his time, but I fail to find any record of extended experiments with these nuts in this country, and as there must be some good reason for this neglect, perhaps my own experience in the cultivation of the filbert and hazel, to be given in succeeding pages, may throw some light on this question.
Propagation.—Filberts are readily propagated by almost all the modes employed in the multiplication of ordinary fruit trees and shrubs. The nuts are not at all delicate, and may be planted in the fall, or stored in a cool place, mixed with sand or sphagnum, and then put out in spring, always selecting a rather light and rich soil for a seed bed, and in such beds plants from one to three feet high may be obtained the first season. The seedlings produce such a mass of fine roots that they are readily transplanted without danger of loss. Varieties are perpetuated and multiplied by budding, grafting, suckers, layers, and some grow quite readily from cuttings made of the young, vigorous shoots, cut up into proper lengths in the fall, and then buried in the ground until the following spring, then planted out in trenches, as usually practiced with currants, grapes and similar plants. The method of propagation most generally practiced in Europe and this country is by suckers, and as the cultivated varieties of the filbert usually produce these from the base of their stems in profusion, there is no lack of material; besides, they make as strong, healthy and productive plants as can be procured in any other way. To secure an extra number of roots on these suckers, they should be banked up with a few inches in depth of good rich soil, or old manure, about midsummer, and then late in the autumn dig down to the base and remove with knife or chisel, after which they may be headed down to about fifteen or eighteen inches, and heeled-in for the winter, to be planted out in nursery rows early in spring. If a greater number of sprouts are wanted than the plants naturally produce, the main stem may be cut down; but this will seldom be necessary, because the young transplanted suckers will usually produce more or less new ones the first season, all of which can be utilized for multiplying the stock if they are wanted.
