I tore off a leaf and took a picture. A comparison above next to a silver dollar.
Not sure what kind mine are, I bought spuds from my local supermarket so its whatever is sold in most US markets.
They do get full sun and I am growing them on a horizontal trellis. So maybe my design of their growing bed is giving me bigger leaves? I grow the spuds in 6-10 inches of woodchips made from ground up trees. It makes it very easy to harvest them. I have also had good luck growing sweet potatoes in old stale hay.
They also get alot of water, Georgia is known for alot of rain. So not sure why mine are bigger.. maybe they are different. When I harvest the spuds I'll take pictures and maybe they are indeed different.
Looking forward to cooking some. I'll probably do some in the next few days. I'd hate to lose most of them turning yellow so I plan on cutting them before.
I just took this a pic at pinterest because there isn't any sweet potato growing nearby (I live in a surbuban area and these things can occasionally be tossed in empty lots and grow wild for free picking, we don't have seasons, only rain or sunshine being near the equator so this one grows all year round). Not a potato expert but your soil probably helped a lot. The leaves are bigger while the ones I know of are more angulated and smaller than the image on this comment. Hopefully they taste just as delicious too (if they do differ in variety from. The ones grown in southeast Asia). Good luck and take care!
Thats awesome they grow all year around where you live. We grow them from spring to fall here and then restart next spring.
Those leaves do look a little different than mine, so maybe its a different cultivar.
What color are the spuds? Mine are red on the outside and yellow on the inside.
Hah I am sure they will taste good, I have eaten alot of the leaves raw and seems just like some stringy lettuce to me.
