Weedy Tendencies of the Japanese Knotweed cont'd

   Because of its underground, creeping stem habit, the Japanese Knotweed may become a vile weed. This underground stem or rootstock develops numerous buds, each of which may form a new plant; thus it creeps from the desired limits, invading the territory of more worthy plants. In the vicinity of State College, Pennsylvania, the plant has become obnoxious in several localities, I have been compelled to fight the weed each spring in the vicinity of my home. The pest is difficult to combat due to the deep-seated rootstocks, which must be carefully dug out. Cutting back the little plants as they come above ground in the spring seems to be of no avail, since numerous others are constantly appearing to take the place of those cut out. If all the plants, including the parent, are kept continually cut back for a period of at least two years, the rootstock must eventually become starved out, since green tissue is necessary in order to manufacture food. A former gardener of the Brooklyn Botanic Garden informs me that he had a similar experience with this plant.
   The Japanese Knotweed is variously listed under such scientific names as Polygonum cuspidatum, Pleuropterus Zuccarinii and Polygonum Zuccarinii. It grows to a maximum height of eight feet, and is rendered conspicuous by the profusion of greenish-white flowers which appear from July to October in the form of long, slender racemes; the flowers and the resulting triangular fruits are very characteristic. The plant is readily identified by the large long-pointed leaves with peculiar bases which has the appearance of being abruptly cut off as though with a pair of shears. The noxious feature, the rootstock, is characterized by begin rather heavy and woody, and studded with many large, often reddish buds, each of which is a potential plant; the rootstocks may be dug out in sections several feet in length.
   On account of its possibilities of developing into a pestiferous weed, those who contemplate using the Japanese Knotweed in the spring planting should proceed with caution. Many of our worst weeds, of which the Orange Hawkweed is a conspicuous example, were originally imported into this country for the purpose of garden cultivation and escaped their artificial boundaries to pester the farmer and become sources of great economic loss to the nation. The presence of the Japanese Knotweed in the garden apparently is a menace which should not be tolerated. Our list of garden plants, which have escaped to become noxious weeds, is already far too large; it should not be added to by this new pest.—
Albert A. Hansen, Dept. of Botany, State College, Pa.

Gordonia—Why So Little Grown?—There are many plants about which I ask myself this question, but perhaps more frequently in connection with our native Gordonia altamaha than any other flowering shrub. It has a great deal of interest, both because of its period of flowering (late fall) and of its strange personal history.
   Here is a shrub bearing large, cup-shaped flowers of white, with clusters of conspicuous yellow stamens resembling as nearly as anything a small single white Peony. In a specimen growing at Garden City, the flowers measure four inches across and they are produced from the end of August until the weather gets too cold in October. The specimen is now six to eight feet high and was planted in the open lawn about three years ago as a small rotted cutting in October.
   It has another attraction, that is the claret-red color of the foliage in late fall. It does not produce its flowers in a large crop, but scatteringly over a period of two months and that at a time when there are very few other flowers to be had for anything in the outdoor garden. The specimen shown in the photograph is growing in Mr. Robert W. DeForest's gardens at Coldspring, L.I. Every once in a while the nurserymen will offer the Gordonia, but it is not generally in stock.
   The plant's individual history is curious. It was discovered alongside the Altamaha River, Georgia, in 1765, by John Bartram, and was introduced into England by his son, William, nine years later and was lost. The second collection was made in 1778 from which all plants now in cultivation have been derived. It is curious that the plant has not been seen in a wild condition since 1790 and the majority of the plants now in cultivation have been derived from the plant growing in Bartram's garden in Philadelphia. It would indeed seem that Gordonia altamaha is an appropriate shrub for American gardens.—

Building a Home.—In renewing our subscription I feel I must write and tell you what a help your magazine has been to us. We are city people with little money, who were determined to live in the country and hoped to make a living there. We rented one place, as an experiment, to make sure we really would like the country. Then we bought a twelve acre fruit farm and loved it but after five years' struggle with lack of help and lack of knowledge, we failed ignominiously and, very sorrowfully, went back to town. Just about the time The Garden Magazine was first published we made another attempt to live out of town. We bought twelve acres of pasture land. It had nothing on it but a few trees and they were so situated that we could not build near them. We subscribed for The Garden Magazine and followed its teaching closely.
   Two years ago we sold that place for an unusual price for this vicinity and we have bought another place with half the money. The new place looked almost hopeless but is now beginning to show the effect of The Garden Magazine's influence. In a short time we are sure we are going to have a beautiful little home—and a living. We grow Gladiolus and Aster blooms for a city florist and small fruits for the city market. Once, three years ago we decided we would not take the Garden any longer but would depend upon our old numbers but we soon felt so out of date that we subscribed again for a three years' term.
   It would take a much longer letter to fully express our appreciation of your magazine.—
F. W. Donaldson, Pennsylvania.

As a Subscriber to The Garden Magazine I have gleaned a great many useful hints in gardening from it and would commend it to all amateurs in gardening. I have a small home in this little growing hamlet and have planned many little ways to make its surroundings pleasing to myself. May your useful magazine continue in the future as valu7able as it has been in the past.—Samuel O. Hedges, Bridgehampton, N.Y.

A Compulsory Gardener.—Being one of the obsessionists who simply have to garden in the compulsory, Kipling, sense, I find the guidance of The Garden Magazine most helpful, and increasingly valuable from year to year. And now comes the pleasure of meeting Mrs. Wilder in the January issue. It makes one wish for more! Mrs. Wilder can make a Poppy note delightful.—A. R., New York.
