The passiflora plant requires well-drained fertile soil and good moisture to flourish. Once established, it grows quickly and reaches about 15-20 feet per year. The plant has an average lifespan of about 5-7 years.
Over five hundred cultivar types of passions exist; however, only two main types, purple and yellow varieties, are widely grown. Banana passionfruit (P. tripartita var. mollissima), known locally as curuba de castilla, features small banana-like shape with rounded ends. During each season, the vine bears greenish-white fragrant flowers which subsequently develop into fruits.
