HARDY PERENNIALS, FERNS, GRASSES, and HERBS 
For Special Herb List, see pages 90 and 91 
You will observe that we list Perennials by threes instead of singly. It is our belief that 
superior garden effects can be achieved only by. grouping at least three plants of a kind 
in borders or rock-gardens. Plants especially suitable for ground-covers or dwarf hedges 
are listed by the hundred rate as well, but we will be glad to quote you prices on other 
varieties in quantity. If single plants are wanted, the price will be one-third the listed 
price for three plants. 
Varieties marked with a black dot (•) are particularly adapted for rock-garden use 
Except where otherwise noted, all Perennials are priced at 90 cts. for 3; $2.40 for 10
