Passiflora Toms Black Passion fruit vine is an amazing plant that produces delicious edible passion fruits. This vine is beautiful but most of all it is grown for the jet black fruit, which is exceptionally sweet. My vine produces 15 to 20 of these beautiful fruits during the summer. Passiflora Toms Black will grow to about 30 feet and will be pretty much pest free. It is hardy in zones 9 and higher. I keep mine in a 14 inch pot to protect it during the winter months. Passiflora Toms Black also can be cut back and brought inside during cold weather. USDA Hardiness zones 9 to 11
