PLANTS VALUABLE FOR USE IN ROCK GARDENS, IN JAPANESE GARDENS, AND IN WALL CREVICES : Page 328

The most interesting group of plants, perhaps, for rock garden work,includes the plants known as "alpine" plants, which are low-growing,very dense, and compact in their habit of growth. Most of these plantshave small leaves and the flowers are rather brilliant and marked intheir colours. The term "alpine" plants to-day is applied in itsgeneral use to that dwarf and low-growing group of plants which have atendency to compactness of habit, and which in their mature form ofdevelopment seem to fit into the confined atmosphere of the averagerock garden. The true rock garden plants may perhaps be the"alpine" types, but those plants which landscape architects useto-day for rock garden purposes include not only the "alpine" typesbut many small plants, even though they come from the lowlands,from the woods, or from the more arid desert sections. There are afew of the tall-growing types of plants, such as foxgloves and someof the single roses, which, though not dwarf in character, are ad-mirably fitted to the scale of rock garden work,
