I didn't photograph the tubers, but I can/will, in the interest of "science"! But it may take a day or two. 12½ hr shifts have their advantage, but they do kick the crap out of a day!
I unfortunately missed a perfect opportunity. The other day, I found one of the tubers I had placed in the pot last year lying on the surface of the soil, sprouting there, What did I do? Of course I just dug a hole and planted it. Never thought to photograph it until a few days later.
In the meantime, if you need a visual, here is a good representation:

I know they're snake eggs, but when I first dug up the tubers in the compost, that's exactly what I thought they were. Too small for black racer, but I figured maybe Ring-neck snakes.
Anyway, I'll get back to you!
