A variety of the common native species (Thuja occi-dentalu). It is a strong and vigorous grower, and apparently as hardy as its parent. The foliage is a rich golden yellow, there being scarcely any green leaves, except in the center of the plant. It is quite distinct from the common Variegated American or Chinese Golden arbor vitae. It is the only variety which we have seen that is really deserving the name of Golden. Where or by whom it originated is unknown to us, our plant being received a few years since from a Mend, who said that it was supposed to have originated in a garden in New Rochelle, N. Y.
For an evergreen ornamental hedge, the Arbor vitae is extremely valuable; for a screen to protect particular plants of a garden, a hot bed, etc, it has no rival; the American is the only one suitable for this latitude and further north. It makes a superb hedge, and is of rapid growth; purchased young, it is economical. It is offered every spring, from Maine, at one cent a plant for one year old seedlings, is easily removed from a distance, and, with the single slight objection of its getting somewhat brown in mid-winter, is among the most desirable for an American ornamental hedge. It will acquire great beauty even without any use of the shears, and is altogether less troublesome than any thing we know. Other Thujas, especially the Stricta are also valuable.
This new variety of arbor vitae, sent out by Messrs. Ell-wanger & Barry, is really a valuable acquisition. It forms a dense mass of fine, delicate foliage, not surpassed by any other hardy variety. It also retains its color well through the winter, not turning a sickly yellow, as many others do, thereby detracting much from their beauty as evergreens. The Tom Thumb will certainly become one of the most popular varieties of the dwarf arbor vitaes.
What distance should Arbor VItae be set apart to make good hedges and screens? What height would the hedge attain when so planted? L. M. F. - St Paul, Minnesota.
Plant a foot apart; two feet will do, but the effect will not be to speedily attained. For a high screen, perhaps the latter distance will be better, as it will give the roots more space to spread in You may have it twenty feet high for shelter; for an ornamental hedge, five feet is enough.
"I propose to make an arbor sixty-six yards in length, six or seven feet in breadth, and nine feet in height. I am informed that Hornbeam is the best tree to use for the purpose. I shall be glad to know about what number I should require for a walk of the size mentioned. And I shall also be thankful for any hints as to planting, training, etc." - G. W. H.
[There is a similar arbor walk at the Stud House, Hampton Court, of great age, full of Hornbeam trees, and romantic legends. In the olden times, trees were planted too thick for these arbors; but the Hornbeam will bear to be planted as close as four feet apart for an arbor walk, - that is, a walk with a row of trees on each side of it, feathered to the ground, and covered over-head with the branches and tops of the said trees. All they require is, to have the ground trenched for them, - say, four feet wide to begin with, and two feet deep].
