A Field of Hybrid Artichokes
The very marked improvement that Mr. Burbank has been able to effect in the artichokes in his garden within recent years has been in considerable measure brought about by crossbreeding different races. Such crossing has of course been followed up by rigorous selection, and the result is a great variety of artichokes of very striking qualities of size and form of flower-head, and of flavor. Some typical specimens are here shown.
