I bought a couple of them today, I'm looking forward to the display this summer. In the fall will they have sweet potatoes that I can use to propagate for spring of next year? Do they flower for seeds? I'm clueless! Confused

I have never tried them from seeds. I know if you cut a stem and put it in water it will root. I grow mine in pots and I leave them in the pots and bring them inside for the winter and they come back.

I have been told that there are little bulbs/potatoes that people take out and store them like dahlia bulbs. I could not find any at the end of summer so I just save them through the winter in the pots.

If you're putting them in fertile, moist ground now, you should have some very nice size potatoes by the time frost hits. You can eat them, or store them to grow again next year. After being dug-up, sweet potatoes need to be cured. I won't try to paraphrase the experts on that:
http://www.ncsweetpotatoes.com/sweet-potato-industry/growing...

Many people report disappointment from harvested sweet potatoes because they skip the curing step. What kind did you get? 'Blackie' and 'Margarita' are delicious, IMVHO. I couldn't tell a difference between those & the kind with normal, medium green leaves, but did like them better just from being jaded about them being "free from the yard."

If you want more plants, just cut pieces of the foliage off & stick in water for 2-3 days until they start sprouting roots. Potatoes from plants started later will be smaller, from having less time to grow. As long as the drainage is good, any potatoes you miss will probably keep growing next year. Definitely hardy here.

Thanks Cinta and Tiffany. I may dig a few in the fall and leave a few, see how they do. Tiffany yes they are Margarita and Blackie. I was in a different nursery this time around, not my typical HD run. My eyes were pretty much popping out my head at the variety of plants. I heard Cinta in the background saying do it Kabs, DO IT!

I've used these as annuals before and am always pleased with them. I love the acid yellow one.
