PLANTS FOR GROUND COVER : Page 550
In one of the former groups of plants for dry locations and for em-bankments, the discussion was directed toward the effects of dryingout. There are instances where the open exposure and the effect ofthe sun develop a situation requiring plants that will withstand ex-treme sun exposure. These plants can be adapted to light, sandysoil, and they form a small group, with the stonecrops, the Adam'sneedle, and the maiden pink as typical varieties, which may be plantedunder the most adverse conditions of exposure and sun.
Quite often one finds plantations of rhododendrons and azaleas whichhave fallen just short of being really interesting because of the lack ofsome ground-cover planting to give the added and desired touch of in-terest. This may be for the purpose of relieving the bare groundaround the edges of the plantation, so often covered in a successfulmanner with Japanese spurge, periwinkles, ferns, and andromedas. Itmay be that one desires a touch of colour so often obtained by theintroduction of the different types of lilies, which can be successfullygrown in plantations of hybrid rhododendrons. Especially in plantingsof large and native rhododendrons, many of these ground-cover plantscan be introduced with a great degree of success to relieve the "leggy"appearance of these plants and to make an interesting mat over theground which might otherwise be more or less bare. The groundamong rhododendrons is subject to more or less heavy shade for two
