=Fastigiate Trees.=—The Lombardy Poplar (_Populus fastigiata_) is at once one of the most conspicuous and picturesque of tapering trees. Though it can hardly be described as a beautiful tree, yet for landscape effect the tall, spiry, column-like appearance renders the Lombardy Poplar of particular value for certain well-chosen positions in our parks and grounds. In the neighbourhood of a town or country village it produces an effect almost akin to architectural embellishment, while in flat or low-lying districts, and particularly near water, it is most at home and probably looks best. It also associates kindly with old ruins and has a pleasing effect when rising out of pointed-headed Cypresses or Yews, but in all cases it is a tree that should be used sparingly and with extreme caution. Forming avenues or lines of the tree is not good taste, while planting single specimens in open situations should be avoided. Of the Poplars there are several upright-growing varieties in addition to the Lombardy, such as the beautiful _P. alba Bolleana_, a desirable fast-growing tree with a character of its own. The Oak, too, has its decidedly upright form in _Quercus pedunculata fastigiata_, which in old parks is a fairly common tree. A decidedly beautiful small-growing tree is the upright form of the dwarf Acacia (_Robinia Pseudo-acacia inermis fastigiata_) which for confined spaces and wealth of delightful pea-green foliage is a valuable small-growing variety. The Elms are not wanting in upright-growing forms, both the English and Scotch being represented, the former in _Dampieri aurea_, and the latter in _Montana fastigiata_. A beautiful and distinct tree of upright habit will be found in the fastigiate variety of the Tulip tree (_Liriodendron tulipifera fastigiata_). _Cupressus sempervirens_, in many parts of England, but particularly by the coast, forms a beautiful tapering evergreen tree with the darkest-green foliage. For clump planting it is particularly desirable, but it is not quite hardy in some parts of the country. Another coniferous tree of naturally erect growth is the red or Virginian Cedar (_Juniperus Virginiana_), which in sheltered sites is a most desirable member of the family. Two other Junipers are of decidedly strict growth, _J. drupacea_ and _J. thurifera_. The Irish Juniper (_Juniperus hibernica_) originated in Ireland, most probably as a chance seedling. It is a most desirable shrub, and on account of its singular habit of growing in a compact, slender and graceful column, has proved itself a most valuable evergreen for almost any position, but particularly where geometrical gardening is carried out. The silvery glaucous hue of the thickly produced foliage is extremely beautiful. The nearly allied but much smaller growing _J. hibernica compressa_ forms a compact slender pyramid of bright-tinted foliage and is an excellent plant for rockwork or small gardens.
