seed potatoes

Potato tubers don't turn to seed, nevertheless, they all can be used to grow potatoes.

If they are grown for seed as opposed to gone past eating it, they are likely to produce a better, healthier quality crop and that's without stating that seed is screened for disease.

what are the tomatoe looking things that grow on the potatoe plant? Is that where they get the actual seeds from in the first place?

It's the fruit of the potato deadly poisonous, the humble spud is a relative of the tomato,and also deadly nightshade.

a "seed" potato is a small tuber grown specifically for the purpose of planting to provide a crop. I'm not even sure if the seeds in a potato fruit are viable.

I used small spuds out of the farmers sacks we buy for years with no problem, but since we had that bad blight attack last year I've bought only certified seed potato's.
