What is that Nub on a Peanut?

A shelled peanut consists of two perfect halves with a little nubbin on the end. If you thought that little tag’s only purpose was to end up as bag crumbs think again! That little nub holds the key to all life…for a peanut that is.


The nub is actually the peanut’s embryo. If you planted the peanut (instead of roasting, toasting and tossing in salt) a new peanut plant would grow out of that little nub and the seedling would draw nourishment from the big peanut part to get it started.

How cool is that?
