I have been wanting to buy some passion flower seeds or starts and from what I read passiflora incarnata is what I want. I did find a website offering seeds from many different "Passion flowers" but not the incarnata although they use it's picture. They offer these: P.Adularia P biflora P.capsularis P. coriacea P.coriacea Wild collected P.edulis flavicarpa P. foetida hirsuitissiama P.foetida hirsuta P.foetida hibiscifolia P.gilberti P.gracilis P.maliformis P.morifolia P.rasticulata P.rubra P.St Rule P.suberosa P.subpeltata How much difference could there be in these from the incarnata? I mean for the herbal benefits. Anyone know?
