Treasure Island Sweet Potatoes are a breakthrough in breeding as they are the first edible and ornamental sweet potatoes on the market. Not only are the leaves colorful, they are edible as well! In the fall you can dig up and enjoy the colorful sweet potatoes. The varieties in the Treasure Island series are named after Polynesian islands. Each plant hides a ‘treasure’ underneath the soil, and the varieties sport different leaf and root colors.
Named after the largest island in French Polynesia, known for its high mountains and surrounding coral reefs, the Tahiti sweet potato is abundant in health-promoting benefits that are delivered through its edible and narrow, dark-green, finger-shaped foliage and its rich purple skin and flesh. The Tahiti sweet potato is the delicious purple jewel growers can’t get enough of.
Grow sweet potatoes in rich fertile, light sandy well drained soil. They prefer an acid or neutral soil in full sun. Harvest sweet potatoes in late summer approximately 10 to 14 weeks after planting, when the foliage begins to turn yellow and die back.
