Sweet Potato Tatakoto Sweet Potato \'Tatakoto\' comes from the innovative Treasure Island Series, bred for both flavoursome crops and ornamental qualities. This compact variety produces plenty of ivy-shaped, dark green leaves with prominent purple veins, which can be harvested as a tasty salad crop. The ornamental foliage makes this a fine patio plant, until early autumn when the plants can be lifted to harvest the purple-skinned, orange-fleshed tubers. This variety makes delicious sweet potato fries and jacket potatoes for your plot to plate dinners. This is a great potato to grow in the vegetable garden if you prefer something a little different, or alternatively, it makes an attractive specimen in your vegetable patio display.
