Found on net: Botanically known as Ipomoea batatas, the sweet potato is a member of the morning glory family, Convolvulaceae and is closely related to the morning glory vine (I. purpurea) and the leafy vegetable, kangkong (I. aquatica). It is not related to the true potato, which is a member of the tomato family, Solanaceae. There are ornamental sweet potato varieties grown exclusively for their decorative foliage. These ornamental varieties may also produce edible underground tubers but they are usually less prolific and tubers are usually smaller and not as palatable as those that have been bred and grown exclusively for their tuber. I would wonder about any possible pesticide used by the greenhouse growers. They can be used to start new plants, they root easily. Never tasted them...Rina

I am a preschool teacher, each year I have my class start a sweet potato plant by placing it in water in the classroom. It will take a few days for it to root then in about a week it will start growing the vine. The vine will grow very fast! When spring comes we plant it in our flower garden. The vine will spread a very long distance. We dig up our sweet potato plant close to Thanksgiving. Last year our one potato produced 25 potatoes of varying sizes. We found several recipes to cook up for lunch. I am sorry I don't know how to attach photos, my students always have fun with this project. We will have to try a sweet potato leaf salad now!

Mr. Brown Thumb says that the ornamental ones have been bred for their lovely foliage so that's why the potato is pithy and woody, whereas the sweet potatoes bred for their potato production are tastier ... in the tuber portion. http://mrbrownthumb.blogspot.com/2010/10/ornamental-sweet-potato-vine.html. Sooo if they're both Ipomoeas then one should grow them for what they intend to harvest and use for their tables ... either leaves or tubers? I have Puerto Rico sweet potatoes growing and will have to try eating the young leaves and shoots. This is a very interesting discussion because I have been curious about eating the foliage for a while. Does anyone know if all Ipomoeas (morning glories) have edible leaves? Thanks to you all for the information in this thread.
