The Pineapple Quince on the Tree
Mr. Burbank's Pineapple Quince, the culminating effort of fifteen years of selective breeding, combines the good qualities of the other quinces with especial properties of its own. It has the flavor of the pineapple, and has such qualities that it may be eaten raw like the apple. It will cook as tender as the tenderest cooking apple in four and one-half minutes. The tree is extraordinarily precocious, sometimes bearing fruit when only four months old. Tiny trees of the pineapple quince are sometimes borne to the ground with their weight of relatively colossal fruits.
