Bought a packet from Menards yesterday, by Burpee, and can't find any real info about it.

Per a conversation with a Burpee representative, they are open pollinated, and are Allium Cepa, but they weren't sure if they went under any other names than "Golden Grande"

So, does anyone know if they do? The closest thing I've come up with is "Grande Gold", but haven't been able to find really anything about that.

Thanks.
