I can taste them!!!!
One year I took the seeds from a whole yellow Passionfruit with flesh and juice and everything and threw them on top of soil. They all germinated really fast without any problem!! I always thought that the acidity in the juice helped along, since I had always trouble germinating them from dry seeds.
I had pots and pots ( took large buckets and punched holes into the bottom for drainage) of plants! That Summer I let them run up the vegetation in our backyard. I had a green wall, but by the end of the Summer still no blooms/fruit in the making. I gave up and gave the pots ( after whacking the vines back to their plants) to a local nursery near our place in Pennsy, which had hopefully more room during the Winter.
