Yes, you can grow them if you can manage to keep them in good condition until planting time. With the usual disclaimers about using non-sterile seed potatoes.

I haven't tried the 'green' potatoes for seed, but I have tried uncertified seed potatoes for starts. In my experience, it wasn't worth the effort. I find that it was well worth the price of certified seed potatoes for the amount of produce obtained vs. saved potatoes. I usually buy my tatoes from Rural King, a mid-western farm supply store, since their prices are usually much cheaper than anywhere else that I have found.

g'day gardener,

yes hey can be used, i also used to advocate using certified potato's to grow from it makes no difference to cropping you either do well or not, but it is supposed to ensure no disease.

i plant both certified and whatever sprouts in the pantry from shop bought potato's i do just as well crop wise with both, there are a lot of gardeners out there who plant shop bought material and to date i can't recall any plant health issues because of that.

can you eat green potatoes? i heard they are toxic

You shouldn't eat green potatoes because they contain Solanine and Chaconine. That said you probably won't instantly die a horrible death, but you might get sick. Green potatoes don't taste very good either.

Keep in mind that if you had any late blight problems last year - and who didn't - the disease carries over in potato tubers. Cornell recommends that no volunteer potatoto plants be allowed to survive and that no potatoes that may have been exposed or suffered LB be used.
