I purchased an assortment of 10 Passiflora seeds on Ebay from Odessa, Texas; Passiflora Alata (Red Passion Vine) Passiflora Mollisima (Banana Passion vine) Passiflora Cerelula (Blue Crown Passion vine) and Passiflora Edulis (Purple Passion Vine. I planted the seeds in peat balls surrounded by damp spagnum in a food container. Three germinated in 12 days and 2 more germinated within 30 days! There has been no damping off, they are now happily growing in a western window in Toronto, Canada.
