This is a seed head of a lettuce plant that is ready to harvest. It grew up in this cold frame this spring. If I let it self scatter, I will have another crop of lettuce in this cold frame in late fall and early spring, if the winter is not too severe. Or to gather the seed, I break off the head and stick it in a paper bag and label the variety. This variety is Green Ice, a frilly semi heading type. The seed will not cross pollinate if there are no other lettuce varieties within 25 feet.
