The look of my Sweet Caroline Sweetheart Jet Black sweet potato vine (ipomoea batatas)

The look of my Sweet Caroline Sweetheart Jet Black sweet potato vine (ipomoea batatas) last 11 March 2019.

The dark purple look of my sweet potato plant.

It cuttings was given by one of my Aunt last 12 February 2019. She did mentioned that this type of sweet potato only used the leaves to make stir fry vegetable dish. The tuber is not much for consumption. Where my findings below👇👇👇 does support my aunt's advise.

While Sweet Potatoes all come from the same parent material out of Southeast Asia, there is a big difference between the Sweet Potato you buy in the store and the tubers produced by the Sweet Caroline and the Illusion plants. Commercial sweet potatoes have been bred for over 100 years selecting for those with the best sugar to starch content (hence the name SWEET Potato), the ornamental have been bred to produce good leaves and no tubers, though they do form, they are composed of almost pure starch and no sugar; making them a poor choice for eating. So yes you can eat the tubers, but don't expect anyone to come back for seconds! Also always be careful when eating any ornamental plant unless you know how it was grown, and if pesticides or fungicides were used on it before you got it; a tuber is a storage root, and yes they store chemical as well as starch.

Till then, have fun planting ornamental sweet potato plant at home😉💪.
