Got a packet each of 'Black' and 'Bramling Pink' peanuts back in the Spring and gave them a try. [bought them from "Sand Hill Preservation Center"] They didn't seem like they were doing much all summer other than making nice healthy foliage, but when I dug them up... they surprised me with just how many peanuts they had snuck down into the ground. If you didn't already know, that's how they do it - each little yellow flower falls off and then the seemingly naked stem grows downward until it buries itself. Then it forms a peanut. I let them dry for a day in the sun and now have them hanging in the garage drying/curing.
First two pictures are of 'Bramling Pink'

I'll try to post more later of the shelled peanuts.
