Passion vine i found in my yard has red bulbs on it...is this the passiion fruit????

The flowers are smaller than regular passion vines, light purple and white and the unripe "fruit" has a thorny looking bush around it...i say thorny ..it looks thorny but its rather soft and the red fruit has nothing on it...I opened one of the red "fruits" and it had small clear seed looking things with black things in the middle...any ideas...i know edible passion fruit only comes from one variety but i dont know what kind??

It sounds like a wild passionfruit. Sometimes the big fruiting varieties are grafted onto wild vines to increase their growth, but the wild types don't bear fruit worth eating. Sounds like the fruit you are describing. easiest way to grow a black passionfruit, is to get a fruit, scrape out the pulp, plant the seeds and wait foir the vine to grow. Can be hit and miss as to weather the vines will be good fruiting types or not.


If you can buy a grafted variety, like "Nellie Kelly" and keep the part from below the graft producing any branches, the vine will grow easily and flower and produce very nice, large sweet fruit.
