Can you clarify what a tuber is?

A tuber is the root of a plant which reproduces by tunneling through the ground and creating big "pods" which repeat the process. Think of a potato. Underground, it shoots off all these little roots, and at some distance, *pop* another potato will grow and shoot off more roots, etc etc etc.

This is the only way these plants reproduce. Root vegetables, on the other hand, like carrots or beets, will typically flower or otherwise produce seeds. The roots grow not for reproduction, but for nutrients, in the same way that a tree's roots grow.

You can buy carrot seeds, or beet seeds, but you cannot buy potato seeds - there's no such thing.
