Wild scallions are growing everywhere. They are edible. But, they won't be as good as farm grown. I threw them onto compost heap.
野葱到處亂生亂長。雖說它們是可吃的, 我認爲還是農場培育的才更好吃。順手丟棄堆肥堆。(想到小時候老師和課本教--對岸同胞吃草根... !!!)
I borrowed these scallion pictures from Rev. Chuang's blog. They enjoyed the food and one day trip to northeast coast-Yilan, Taiwan. What a treat they shared.
