This may look like a common, ornamental Sweet Potato Vine, but this particular variety produces delicious tubers!
Introducing Treasure Island Sweet Potato Vines. Just like the ornamental, the foliage is lush, dense, and compact, and the plant itself thrives in container gardens alongside other flowers; but come early fall, you get to harvest edible sweet potatoes. And the leaves are delicious, too, similar in taste to spinach.
It takes about 120 days until harvest, the fruit is about four to six inches, and the foliage can trail upwards of five feet. Keep in full sun, and weed the area regularly so the roots don’t compete for space, water, and nutrients alongside the tubers. Follow our watering schedule to establish the plant, and water more regularly as they mature to encourage a larger yield. And don’t use excessive nitrogen, this can alter the taste; try a balanced fertilizer.
Overall, they’re pretty easy-care and so beautiful for a fruiting plant.
