The yellow passion fruit, Passiflora edulis f. flavicarpa, cultivars and flower biology

The Passiflora genus contains about 400 species but only a few have developed commercial interest for fresh consumption, industrialization or ornamental purposes. The passion fruit is the species more commercially developed. Only a few of the Passiflora sp. are well known in the Caribbean. Of these the most popular are the yellow passion fruit, Passiflora edulis f. flavicarpa, and the giant granadilla, Passiflora quadrangularis. In some Caribbean countries the belle apple, Passiflora laurifolia, and the sweet granadilla, Passiflora ligularis, are also well known, but only the yellow passion fruit and the giant granadilla are grown commercially.
