We have these wild onions that grow all throughout our lawn. My pet theory is that this readily available smörgåsbord is what keeps the bunnies coming back. No matter how hard I've tried, no matter how many little onion bulbs I've pulled up out of the ground, I cannot get rid of them and they multiply faster and faster each year. After a couple of years we just started picking, cleaning and chopping them up to serve on potatoes with sour cream. They're not bad. If you can't beat 'em, join 'em.
