‘Rock g ardens 
o other form of horticultural hobby has achieved such popularity 
as rock gardening. The wide range of effects duplicating Nature appeals to 
almost everyone and a rock garden is successful only when the rules of Nature, 
both from the standpoint of design and growing requirements, are closely 
followed. 
A rock garden may be constructed in any location in either sun or shade. 
There are groups of plants which thrive in the driest, most gravelly soil and 
those whose roots love the coolness of moist, leafy humus. 
To enjoy all of the features of rock gardening, a large area must be devoted to 
it. However, attractive effects may be derived from limited spaces. In the 
shady rock garden, many of the delicate woody plants will be a delight in the 
spring with their myriads of charming blossoms. In the spring and autumn, 
the dry rock garden will reach the height of its beauty, requiring, as it does, the 
use of alpine plants and fall-blooming flowers to complete its long sequence of 
bloom. 
So natural an effect has been- achieved here that Nature and not man might have conceived it.
