LARGE LEAVED CLAMP 60 
Sometimes called Lamb's lettuce. An extremely hardy type plant that forms rosettes of 
tender leaves which are used as a substitute for lettuce and mixing with salads. Leaves 
are large, rounded, and thick. 
SWEET CORN 
Zea Mays—var. Rugosa 
Sweet Corn seed of today is the result of the most highly developed and controlled’ process in 
the garden seed industry. We refer specifically to the Hybrids and Top Crosses now available 
which are made to fit particular conditions and requirements whether it be for canning, shipping or 
local marketing. 
After years of inbreeding by the tedious task of hand pollination, pure inbred lines are developed 
to then be combined by cross pollination to produce the Hybrids. Our breeding operations are 
designed to develop, maintain, and supply the best Hybrids and top crosses for our customer's 
requirements. 
The performance of adapted Hybrids in comparison to open pollinated varieties is astonishing. 
The vigor, disease resistance, uniformity of maturity, resistance to lodging, quality, and productivity 
is truly outstanding and justifies their widespread use and increasing popularity. 
The number of days shown to reach the edible stage represents an average over a period of 
years at our St. Louis trial farm and may be expected to vary in different sections of the country.
