Most veggie gardeners grow lettuce, spinach, and perhaps chard, kale or collard greens. Some are familiar with bok choy (spelled a dozen different ways). It’s the adventurous gardeners, or those from overseas, who include veggies such as Mizuna, Salt Wort, Fun Jen, or Yu Choi Sum.
Since we used to live in Cupertino, California, where my local grocery store was Tin Tin #2, and the closest restaurant served the most incredible mu shu pork and lettuce wrapped chicken, it was only natural that I included some Asian imports in my garden as well.
I admit to having western taste buds, so what I recommend might seem all wrong to someone used to more exotic flavors. However, I like what I like. Maybe you will too.
