Wish I could have made this one. Thanks for the heads-up.

Old thread but curious to know how it went. Yellow passionfruit could be either sweet granadilla (passiflora ligularis) or yellow passion fruit (passiflora edulis var flavicarpa). Around here, sweet granadilla seems more common at grocery stores - I started growing a couple plants from grocery store fruits. I'm also growing purple passionfruit (passiflora edulis), passiflora manicata and passiflora tripartita var azuyensis. Neither of these are frost hardy and require more than a year to fruit, so I'm growing them in containers that I bring indoors for the winter. I also have maypop (passiflora incarnata) and bluecrown (passiflora caerulea) which are a bit more cold hardy (if you plant in-ground, the vines will die back in the winter, but the roots can survive and put out new shoots in late spring/early summer), but I decided I'll grow those in containers that I bring inside too. I have gotten fruit from my maypop already. So far, they seem to be enjoying their first winter indoors and have gotten quite large. Hopefully they can hit the ground running and produce fruit next year. It seems plants grown from cuttings will produce fruit within 1-2 years, plants grown from seed will produce fruit within 2-3 years.

I pick my fruit when the skin gets a little soft. Then I let it ripen indoors (they get softer and start to wrinkle). They will taste good freshly picked but seem to get sweeter if you ripen them. I found if I leave then until they drop, there is a little hole, like some beetle or bug invades them. I do consistently water them either daily or every other day. I read that the pollen is heavy and bees are the best for pollination. If you don't have bees, you can manually pollinate them. We have lots of bees in our back yard. We have flowering plants (veggies and flowers) almost from spring time until fall to attract pollinators. The pasion flowers require pollination for them to bear fruit.

It's pretty amazing that you got fruit from it at all.. I tried a few different varieties and only 1 ever grew fruit for me and they were normal size, but only 2 fruits total have grown from it in about 4 years. The variety I grew didn't have young fuzzy fruits, they were always smooth.
