I would say yes. The photos you've submitted really say sunroot to me, and your photo of the tubers really clinched it for me.

Thanks, Dave.

I'll close the thread and get photos in the DB soon. It's a very nice Autumn day today after the thunderstorms of early A.M., so I'm going work outside for a bit first.

(I'm glad this plant ID is done! )

For your convenience, here's the plant in the DB:

Sunroots (Helianthus tuberosus)
