Yes, I have grown them. They will be smaller than you may expect, but they do well. I plant mine very very early and leave them outside...they can also be sown under "tents" earlier in February and frost cloth used if needed. I use the tenting to keep the soil warm. I've grown onions from starts and I find that transplanting can slow them, but not much more than planting them in the fall and harvesting in the spring (winter will slow growth too). They are lovely little onions for fresh eating.
