passiflora fruits

I am looking to get seeds or a plant of a large fuiting type of edible passiflora.
I know nothing about the passiflora so I was hoping you might have a few suggestions on what I can look for.
Here in Florida we have one that has run amuck, pretty but has taken over large disturbed areas. I don't know if this type is edible or not or if it even produces fruits. I am looking for one that has known very large edible fruits.
Once I get a few types mentioned here from you all the passiflora experts, I can go on a hunt.

Thanks for your help :-)

p. Edius is a good one

granadilla gets really big. possum purple tastes really good. you wait for them to get purple spoon out the jelly like seeds put in a blender with a few cups of water blend and strain. the best part is all the seeds go to the bottom so you can dry them. i have some seeds if you want to try.
