HI, I'm wondering if you've ever eaten the fruit or made juice or tea from your passion flower fruit? I've often heard of it being used like that and wondering what your experience has been. Thx, Xtal

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 had miraculous results with lillikoi (P. edulis flavicarpa) seeds my friend gave me from Hawaii that were a year and a half old and stored encased in some masking tape :) I scraped one long edge of each seed with fine sandpaper (220 or so) several times until I felt like I had almost scraped all the way through the outer shell. I then soaked the seeds in a small amount (1.5 tablespoons or so of each ) of fresh squeezed orange juice and strong black tea. I placed them in a small plastic souffle cup on a heat mat in a sunny window where the liquid proceeded to evaporate. After about 24 hours the liquid had been reduced to almost a syrup, and I added enough water to get it back to the original amount. After 48 hours I planted the seeds about a half inch deep in half miracle grow seedling starter mix and half perlite, and encased the container in a large bag with the top slightly open to trap the humidity, and placed this on the heat mat in the sunny window. Because it was so hot over the week (sunny, humid and around high of 95F) I checked the soil temp and it was around 97F so I stopped putting the heat mat on during the day, and only put it on at night. Then over the weekend, I went on vacation and accidentally left the heat mat on during the day. When I came back from vacation, one of the seeds (a year and a half old!) had already sprouted.... this was only 7 days after planting!!! Within 3 days, two more had sprouted. I am not sure if these results were because flavicarpa is particularly hardy and vigorous, if there is something about storing them stuck between masking tape that preserves viability, or if it was the pre-treatment effects and warm soil that made them so viable, but whatever the factor, I am pretty pleased with this ultra fast germination and wanted to share in case anyone else can use this info :)

I was able to get over a dozen fruit from my maypop passionflower in Ontario. Also grown in container. I set it out along a fence outside in the summer so it has space to grow. But the fruits had to ripen indoors (on the vine, which I kept in a south facing window) because they ran out of outdoor growing season. I grew them from cuttings, which can result in fruits sooner than plants from seed. Maypops are self-sterile, so I had a bluecrown passionflower to pollinate it. I have other species (edulis, tripartita, ligularis) which will begin their second season now, no fruits yet, but hopefully I'll get some in 2024, since they are a pretty good size and should hit the ground running this summer.
