ROCK-PLANTS—Joyful and Permanent 
The rook-garden offers a delightful medium of expression to the amateur. It kindles the imagination with a flame that en¬ 
riches our garden experiences. So subtle and yet powerful is its influence that once “touched,” we are zealots forever. With Nature 
showing the finest examples of rock-garden design, our problem has been to assemble a distinguished collection of alpine jrlants, to 
furnish color over a long period. The following pages list plants of proved hardiness. They are rugged, permanent, and pictures<iue. 
Given rea.sonable care and proper soil conditions, they should increase in beauty with each passing year. 
Prices of all Rock-Plants in this list, except where otherwise quoted, $1 for 3, $3 per doz. 
Orders for less than 3 of one variety cannot be accepted.
