All of the tops of my "White Potato Onions" from Texas have begun toppling over as expected; when they are fully yellowed I'll pull most up to see if I got bulb formation. I'll leave the rest in the soil in their container gardens to see if they rot in the summer rains, or survive and re-emerge some time this fall. My plants of "Eliska's Bunching Onions" are growing like crazy and continue to remind me of my strain of Allium fistulosum, which functions as a perennial, multiplying scallion.
