Not much luck with lettuce so far, I may try some Pak Choi ...Pak Choy, Bok Choy ? You know, some of that oriental green stuff. There seems to be a little confusion on what to call it, but it looks really nice and I am glad to hear it germinates quickly. Have you eaten it before, is it similar to lettuce?

I let my Pak Choi (it has various spellings) get pretty big, it kind of looks like "fat" celery. The flavor is mild, not quite like cabbage, sort of more on the broccoli/kale flavor end of the spectrum. Very mild. Not at all like lettuce to my taste, but I know people do use it in salads. I prefer it steamed or stir fried. You can use the big leaves as wraps like for egg rolls. A lot of folks do grow it to harvest when young as a salad green. And yes, it fairly flies out of the ground to germinate. You don't need to put heat under it...just plant it and stand back.

We usually add it to boiled meat, either beef, pork or chicken with whole black pepper corns and onions, with some potatoes too. Makes for a nice cold weather soup! In our Filipino language we call it pechay, and the lighter green one is called pechay baguio. I had to call my mom before and ask her what the heck is bokchoi

The lighter green colored one we often used also to line up plates with oily deep fried food, like egg rolls.
