Seeds from this passion vine Passiflora Edulis Purple Granadilla. This passion vine produces lots of these large sweet purple passion fruits in the spring. The vine grew to about 30 feet and was pretty much pest free. The caterpillars are not a problem with this variety. I keep mine in a 20 inch pot and protect it in the winter months with just a light blanket if temps get if the teens. Zones 8 to 11.
