Of every plant that will come true from 
seed, you will find seeds offered in the fol¬ 
lowing pages along with the plants. 
The seed is either that of finer specimens 
saved here in my own garden or is a portion 
of the seed I buy for my own sowing. Superior 
in every case.

SECTION 2. 
Hardy Perennial and Rock Plants 
Old world gardeners have long recognized the importance 
of Hardy Perennial Plants in the garden, and here in Amer¬ 
ica we are coming more and more to appreciate their great 
value. Long lived, with moderate care they bring a maximum 
of beauty over a long period. They range from the tiniest 
alpine to the stately plants for the background of the border. 
Careful selection will give a wealth of flowers from earliest 
spring to late fall, with a few even in winter. They are most 
effective planted in groups, in smaller gardens, 3 to 6 of a 
kind; in large gardens, in groups of a dozen. 
Old friends will find a change in the arrangement of this 
catalog. All plants suited to rock gardens and all border 
plants are now listed alphabetically in this section so that 
you will not be bothered consulting an index to find plants 
of various types. The text, and stars before items will indi¬ 
cate the purposes for which each plant is suited. 
SPECIAL OFFER: Where selection of varieties is left 
to me I will give $6 worth of plants for $5.00; $12.50 value 
for $10.00. For larger amounts 25% additional value will be 
sent. Such selections can be made for: Perennial Border; 
Rock Garden; Shaded and Difficult Corners. Just state your 
problem and soil, and other conditions when ordering.
