A friend of mine grows perennial onions and I asked for one. I planted it in the corner of a bed at my community plot. But I'm still confused about what on earth this is.... I'll have to ask more questions next time I see her.
I have read about perennial onions at Bifurcated Carrots. OK. I guess they are like chives, but they make bulbs as well as greens. Sounds reasonable. And they also make top sets that are like little onion bulbs that can be planted for more onions. OK. Patrick also writes that their best use is for green onions. Super. I'll look forward to this.
Right now its just a scrawny single onion stem. I assume it will turn into a clump after a while. Another new veggie to watch!
