Rock-Garden Plants 
Rock-gardens have become very popular in America, and lawns and back yards 
from the Atlantic to the Pacific are being rapidly transformed into miniature moun¬ 
tain ranges, rocky cliffs, and stone-piles, as the genius and resources of gardeners 
permit. 
One of the hindrances to successful rock-gardens in this country is the lack of 
interesting and beautiful plants to grow in them. Too many people plant annuals 
and border perennials in the rock-gardens, losing the entire effect and half the fun of 
this fascinating hobby. 
True rock-garden plants are usually natives of stony places and thrive to perfec¬ 
tion only when given similar accommodations in the garden. We have assembled 
here a good collection of representative rock plants, which combine both variety 
and dependability. 
To build a successful rock-garden, a slope or bank is almost necessary to permit 
laying up the stones to make the proper crevices. A dry wall, made very thick at the 
base and sloping backward 3 inches to every foot of height, is an excellent substitute 
for a rock-garden, and may serve a useful purpose. Dry walls are built of rough stones, 
undressed, laid up in good rich soil without mortar. 
The invariable rule of rock-garden construction is to lay all stones on their broad¬ 
est face and tilt them all backwards so that rain will run into the earth instead of off 
it. Try to imitate a natural ledge with only a very small portion of each rock above 
ground. The stones are put in for the prosperity of the plants and not to look at.
