We feel that every seedsman who expects to be a leader in the industry must maintain carefully conducted trial grounds where he may 
study new introductions and compare them with standard varieties. He then is able to judge their value and many times protect his 
customers from the person, we will say, who at times seems over enthusiastic about some flower or vegetable. Gordon Jones, in charge 
of the Seed Farm trials, is calling Joe Robson’s attention to a new shade of color he had found in Pink Queen Spider Plant.

SELECTED VARIETIES FROM OUR TRIAL GROUNDS 
Our flower seeds are especially selected for the home gardener who enjoys having a succession 
of bloom throughout the summer. ‘Jo determine the varieties that will give the most satisfactory 
results in the garden we conduct extensive trial grounds every year on our farms. Any varieties 
found to be unsatisfactory are discarded. We feel that this testing program is necessary, even 
though a considerable expense to us, to be certain our customers receive the best flower seed that 
can be found anywhere. 
The flower seed section of our catalog is divided into two parts. Annuals are listed alphabeti- 
cally on the following pages and perennials will be found on page 53. To help you select the 
flowers for your garden we suggest individual uses in the variety descriptions. 
For earlier bloom, most annuals benefit from an early sowing and a single transplanting in- 
doors. Sowing dates are given to provide plants ready for the garden after danger of the last 
killing frost which is about May 20th in our area. If the last killing frost occurs earlier or later 
in your locality, move ahead or delay the starting time. The best time for planting direct to the 
open ground is also given. 
All of our seeds are tested and germinate well in a loose soil when kept moist. Before sowing 
any seed the soil should be thoroughly spaded and the top layer finely pulverized. If the soil is 
not naturally loose, thoroughly mix % to 1 bushel of rotted manure, peat moss or leaf mold into 
each square yard of soil area to a depth of six inches. 
Very fine seed is barely pressed into the soil, larger seed is covered only twice its diameter. 
To keep a good supply of moisture in soil where germinating seeds, cover the rows with a piece 
of burlap or even newspaper held in place with small stones along the edges. Remove the cover- 
ing as soon as seeds start to germinate. 
You will probably sow seed too thick. Be sure to thin seedlings rigorously to the distances 
given in variety descriptions. 
Your plants will look much better all summer if you keep old flowers and seed pods picked off.
