Vigorous climbing vine that produces abundantly in warm climates. Purple passionfruit (Nellie Kelly, Pandora, Sweetheart) is the standard Australian backyard variety. Yellow (Panama) types are more tropical and disease-resistant but more acidic. Grafted plants on disease-resistant rootstock (usually P. caerulea or Panama Gold) are strongly recommended as ungrafted purple vines are susceptible to Fusarium wilt. Vines are relatively short-lived (5-7 years) but produce within 12-18 months.
