That chickweed (Stellaria media) really is incredible at being able to grow anytime it's above freezing in the winter, at least here in Oregon's Willamette Valley. I think it tastes like a simple lettuce. The one, to me at least, that tastes more like corn, is Cleavers (Galium aparine). It's still pretty tiny, just waiting for a little longer daylength! So many good greens! :D
