Very cool - I planted a couple last year and they came up this Spring and are really fascinating.... going to hold off eating then this year and just plant the sets (is that what they are called?) to up the number for next year... the way they grow a whole other plant almost off the top though is really interesting
I'm actually not even certain how to harvest. I guess the greens can be used as green onions, but do you eat the sets at the top? Or is there a bulb in the ground? (something something meme...but now I'm too afraid to ask)
I believe the whole plant is edible, but I was planning on pulling the plant for the bulbs (which should be shallot sized) and re-planting the sets for next year.
