Are you growing this to harvest the potatoes? If so, I'd put a bit more soil over that. When the light hits it, it makes too much of the toxic alkaloid (and why potatoes should be stored in the dark.)

Thanks Tiffany, I will add more soil, I'd really like to be able to harvest them.

TY, Tropic! Fired up the google (which I usually do when there's technical issues like this one, but went with false memory instead) and sweet potatoes are actually cured in the sun to be able to store them for longer. I think I was having mixed memories about latex in Ipomoeas and solanine in Solanums, and how they manifest in relation to light.

That said, toxicity is somewhat relative. I'm sensitive to getting a contact rash from Solanums, like from touching tomato leaves or purple nightshade vine, and to getting a rash like poison ivy from latex sap in Ipomoeas & so many other plants. Awkward, I can eat them, but not harvest them. In my mind, they're both in the toxic category, until cooked. TY for inspiring more research & keepin' it real.

Just to be clear, this is an ornamental sweet potato vine, which is different than an edible sweet potato. It will produce similar tubers but they are not very good to eat (bitter and unpalatable - not at all sweet). I would consider harvesting them to start new plants from but I doubt you would want to include them at the dinner table :-)

I've tried several of the ornamental ones, they're delicious. Tricolor, blackie, margarita. They're all I. batatas. Have you tried them, GG?

I'll give them a try anyway, I'm adventurous, Thanks for that info gardengal ..

Well the cold killed off the vine and here are the potato's

You can eat 'em, or try to save them over winter to grow again in the spring.

Sweet potato pie!

LOL teen, I'd need alot more potato's, Do you have a good recipe, I love sweet potato pie,but cant find a good recipe !!

I know, just joking, lol. I wish I knew a decent recipe I love it! I grow the ornamental potato every year and store cuttings over winter in water. I did eat the tuber once, it wasn't particularly bad
