LETTUCE Heading Varieties 
Lettuce is one of the garden seed items most in demand, and our assortment of 
varieties enables us to fill the requirements of dealers who sell to market gardeners as 
well as to home gardeners. The days to maturity refer to the number of days required, 
from planting in the open ground, to produce heads or loose leaf clusters of satisfactory 
size for table use—Minnesota weather the basis of maturity comparisons.
