Harold,
I just did a google search and one of the first items listed was a post you made over on DG.

I think the Tohono and the I'itoi's are the same onion.
Mine Look identical to the one in the picture and they are the ones I gave to Dan.
Do your Tohono's bunch?
How about flowering? The ones Dan and I have rarely flower and die back in the summer but come back during the cooler months.
Does it sound like yours?
