The usual color is orange-yellow, but some 

 varieties have a purplish tinge, and a purple pulp. 

 Some of the species of the Southern Hemisphere 

 are recognized as producing valuable fruit, par- 

 ticularly for combination with other fruits, having 

 a pleasing and unique flavor. But the fruit of the 

 Maypop has seldom been considered worth 

 picking. 



My experiments with the passion flowers began 

 about 1895. I found it not difficult to grow the 

 plant from seeds received from different regions. 

 It is only essential to keep the ground warm and 

 moist. There is an astonishing difference in the 

 growth and vigor of the different seedlings. More- 

 over, some of the vines produce ten or even twenty 

 times as much fruit as others, and the flavor of 

 the fruit varies from exquisiteness to entire insip- 

 idity. Some specimens have a large amount of 

 edible pulp, while others are made up almost 

 entirely of skin and seeds. 



The seedlings usually bear during the second 

 year, or at latest the third. 



The fruit does not ripen to advantage unless 

 the weather is very warm. 



So from the outset I selected those seedlings 

 that bore earliest in the season, attention being 

 given also, as a matter of course, to the size and 

 flavor of the fruit, and to the attractive qualities
