During our fifty-two years of service to American garden lovers, we have always main- 
tained a reputation for seed of superior quality. The success of our many customers in 
growing superior plants has strengthened our conviction that we shall supply only those 
varieties and strains of finest quality. 
In the pages that follow, all of our flower seeds are arranged alphabetically. The 
annuals, biennials, and perennials are carefully marked so that those who are not familiar 
with the different kinds of plants will not be confused. 
Annuals. These grow to maturity, bloom, ripen their seed, and die the same year. 
Asters, Poppies, Sweet Peas, Morning-Glories, and Zinnias are typical examples. Some 
of these Annuals are sown in a sunny window indoors, or in a hotbed or coldframe from 
March to May in order to get an early start. Seed of practically all Annuals can be sown 
in the open ground after danger of frost has passed. 
Biennials. These are raised from seed started in early summer, flowering the second 
year, after which they die. Typical examples are Pansies, English Daisies, and Canter- 
bury Bells. 
Perennials. These plants live on from year to year, increasing in size and in beauty 
with age. Typical examples are Aquilegia, Delphintum, and Hardy Phlox. Many 
Perennials may be grown from seed, which is usually planted outdoors from June to 
September. The young plants may be carried over the first winter in a coldframe or they 
may be set in their permanent places im early autumn and given alight protective mulch the 
first season. Some Perennials are known as half-hardy and require winter protection each 
season, and those known as Tender Perennials require greenhouse protection over winter.
