HERBACEOUS PERENNIALS — BLOOM CARRIED THROUGH 



SUMMER 



I— Adonis Amurensis: bird's eye; nine inches high; any soil, 

 Hght and moist being preferable ; does equally well in sun or 

 part shade; foliage femlike; flowers broad and yellow; 

 blossoms in April. 



2—Pcsonia officinalis: peony; eighteen inches high; rich soil — it 

 cannot be too rich nor too much enriched, for peonies are

 effective ways of using phlox, where there is space for so 

 many plants ; in such a planting all inharmonious magentas 

 must be kept out and only the gradually deepening pinks

 flower heads off as soon as they have faded ; this will insure
