ELÆAGNUS PUNGENS (Kew).
The habit of some of the weeping trees can be directly turned to account in the making of arbours and pergolas; for by planting the large-leaved Weeping Elm or the Weeping Ash at the back and on each side in the case of an arbour, or alternately on each side of the walk for a pergola, a living shelter may be made in a very few years. The trees in this case are standards pollarded at about 8 feet from the ground, the form in which they are generally sent out from the nursery.
CORNUS MAS VAR. VARIEGATA (Variegated Cornel).
Among evergreens the Holly is invaluable. As a rule the weeping or pendulous varieties are budded on tall stems of the type, and trained out in an umbrella-like fashion, thus forming a hollow mound of greenery. In some places, notably at Brookwood in Surrey, pendulous Hollies have been allowed to grow without any attempt at training. Stout stems 10 feet to 12 feet high are surmounted by irregular heads, which droop down 6 feet or 7 feet, leaving several feet at the base of the stem bare. In winter the long pendulous branches, smothered with bright red berries, are very pleasant. Facing page 248 is an illustration of a weeping Holly (I. Aquifolium var. pendula) at Kew. Of variegated weeping Hollies there are Argentea pendula (Perry's Weeping), with silver variegated leaves; aurea pendula (Waterer's Weeping), with gold variegated leaves; and pendula tricolor. To encourage height rather than width, it is often necessary to tie up a few of the top shoots, otherwise they get out of shape; they increase more quickly in width than height.
