Onions

There's two varieties of onion in this bed. One of them seems to be thriving, the other seems to be dying. If I knew which plants were of which variety I could be more certain that it was a variety problem and not an individual plant problem. But I, quite literally, do not know my onions. They were labelled when they were planted in the greenhouse but repotting saw them moved around like the pea in a shell scam so now I have no idea. But there's living plants still in the greenhouse so as a withered corpse gets removed, a healthy substitute is popped in its place.
