I have a passaflora f. or anyway thats how the seeds were labled!

I thought it was an edible passionfruit, but it is different that my others? I have NEVER had one with fruit before?

It has a softer leaf, light green in color, instead of the large waxy green leaf, it blooms small white flowers, and puts on fruit about the size of a large grape, it starts out green then turns yellow. When you open it it has seeds covered in pulp??

Is it edible? How is it used? Can anyone tell me what I have and all about it!

Thank You for any help??
