Price for above: 35c each; $3.00 per dozen; $22.50 per 100. 



THE "IMPERISHABLE" PERENNIAL BORDER COLLECTION FOR $22.50 



A succession of bloom and a very picturesque effect may be obtained by planting the "Imperishable Collection." 



A sketch plan is shown. To make one like it 5 x 50 feet w-ould require 100 plants. We list below 30 varieties of contrasting heights and colors and the number of 

 plants for each group. The number after each variety gives the position in which they should be planted. If out of any variety we substitute a similar sort.
