The Old-Fashioned Hardy Flowers 



The garden or border of Hardy Perennials is about the 

 most valuable and lasting asset of the flower garden. An- 

 nuals, flowering bulbs and even shrubs may be dispensed 

 with more consistently than these old-fashioned Hardy 

 Perennials which for so long a time made the charm of 

 the old-time gardens. 



There is no spot so unfavorable, no soil so sterile or 

 harsh that some flower of hardy nature may not be found 

 to adorn it and thrive and grow more and more orna- 

 mental as the seasons come and go. It is well, however, 

 to enrich the soil before planting with some well-decom- 

 posed manure, dug deeply and well pulverized. 



Secure field-grown clumps in the spring or fall. Plant 

 them well into the soil and as soon as they have had two 

 or three good frosts, and just before the ground freezes. 



cover with about three inches of leaves, nature's protec- 

 tion. Remove gradually in the spring. Do not overcrowd. 

 A very good rule to go by in planting is to set the plants 

 one-half the height they attain when fully developed. For 

 example Delphinium, which grows three feet high, should 

 be planted eighteen inches apart. 



We list the different varieties in groups, according to 

 their blooming period. Thus one may have some of these 

 flowers blooming from early spring until late fall, up 

 until freezing weather. 



The figures in description indicate the height of the 

 plants when fully grown. 



We offer strong, field-grown clumps at 20c each; $2.00 

 per dozen, postpaid; all one variety or assorted.
