Those are nice looking!
I'm also growing shallots from seed this year. These were a commercial variety of shallots, planted as bulbs, that produced seed, and someone saved and sent them to the swap. No idea if they were a hybrid or not, so I thought it might be a mix of onion/shallot segregating, but there are more dividing than not!
I'm pretty stoked about that. Still a long while to harvest though.
It's also possible that going through winter in June has triggered them to do the second year thing...
