The Passion Flower
The Passion Flower is best known for its very curious blossom, a good example of which is here shown. For the most part the merits of the plant as a producer of fruit have been neglected. Mr. Burbank, however, has been experimenting widely with different species, and has developed the fruit until it gives good promise, although it is not as yet at a marketable stage.
