LARGE LEAVED H 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, of a gray-green color. 
Mais SWEET CORN ¥2is 
Zea Mays var. rugosa 
Sweet Corn seed of today is the result of the most highly developed and controlled 
breeding process in the garden seed industry. We refer specifically to the Hybrids now 
available which are made to fit particular conditions and requirements, whether it be for 
canning, freezing, shipping, local marketing or home use. 
After years of inbreeding by the tedious task of hand pollination, pure inbred lines 
are developed then to be combined by cross pollination to produce the Hybrids. Our 
breeding operations are designed to develop, maintain, and supply the best Hybrids for 
our customers’ 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 Keystone Valley Farm trial grounds and may be expected to vary 
in different sections of the country and with different seasons. It is valuable for comparison 
chiefly. 
While sweet corn is a warm season crop, it is desirable to have the harvest season 
come during a period of cool temperatures, since quality is retained longer under these 
conditions. Shallow cultivation is practiced for weed control since many of the roots of 
corn plants are near the ground surface. Seed treatment is an added insurance for suc- 
cessful production.
