I don't know how these papaya are suddenly appearing but I figure birds are dropping seeds? So far six have sprouted, one female, a male which I used to pollinate the female then pulled it and a herm with one fruit.
Funny the only papaya nearby has LONG interesting slim banana shaped fruit and these in my yard have round. Weird.
Anyway one seedling (about 5' tall) is odd. Every leaf has a dark purple stem and purple leaf veins like a person.
I've grown papaya a long time and never saw a banana fruit or one with purple stems, are these common?
