I remember in my childhood my mother used to plant this pak-choi in our front yard in Delles, Burgos, and those soldiers(CAFGU) come to purchase them. They like to sautee it with these dried small fishes or let say anchovies. Petchay/ Pak-choi has various kinds. I noticed that this kind survived the extreme heat of Texas. These plants need partial shade during the summertime. That is why I recommend it.
