RUBUS PHOENICOLASIUS has spread in cultivation recently, and has beautiful scarlet berries. It is hardy enough, but birds are so attracted by the bright colour, that it requires protection from them when in fruit.
SAMBUCUS.--The scarlet-berried Elder, _S. racemosus_, is by far the handsomest of the genus, but although it flowers freely enough, it is very uncertain in producing its fruits. _S. glauca_, from the West United States, produces large, flat clusters of blue-white berries, and there is a striking white-fruited variety of _S. nigra_ called _leucocarpa_.
THE SNOWBERRY (_Symphoricarpus racemosus_) should always have a place in the garden for the sake of its clusters of large pure white berries, which remain long on the plants.
VIBURNUM.--There are several very handsome fruiting species in this genus, no finer, however, than the native _V. Opulus_, or Guelder Rose, with red fruits, and its variety _fructu-luteo_ with yellow ones. In the other native species, _V. Lantana_, they are at first red, ultimately black. Several of the Viburnums are noteworthy for the blue or blue-black fruits; of these are _dentatum_, _molle_, _cassinoides_, and _nudum_. Those of the evergreen _V. Tinus_ are also dark blue, but, as with the other blue-fruited species, they are not frequently borne in profusion in the average climate of Britain.
VITIS HETEROPHYLLA and its variety _humulifolia_, bear singularly beautiful clusters of pale china-blue berries. To induce them to fruit freely, however, the plants require a warm, sunny wall, and rather restricted root-room.
It is not at all easy to define special uses for trees of weeping habit, but it is safe to use them nearly singly and not in immediate connection with trees of quite upright form. The point in the weeping tree is a certain grace of drooping line, such as one enjoys in the drooping racemes of many of the papilionaceous flowers such as Wistaria, Laburnum, and Robinia. Nothing is gained by accentuating the peculiarity by a direct association with trees of an opposite way of growth. It is better rather to place the weeping trees near rounded masses of shrub and small tree--for example, a Weeping Birch would group well with a clump of Rhododendrons.
