Henderson's Perennial Flower Seeds for Summer Sowing. 



Hardy gardening is becoming more popular in America every year. To meet this increasing demand for seeds of 

 perennial plants we append a list of the leading sorts, most of which if sown this summer will produce plants that 

 will flower next season. Biennials grow from seed one year, bloom and die the next. Perennials last for several 

 years, blooming annually from seed after the first season. Cultural directions are printed on the packets of seed.
