They can grow wild here and the state nursery used to produce and sell them but quit doing it. They seem to require a niche little growing spot as they’re an understory tree and like it moist but not wet. Also picky about soil makeup. Same as any forest food, hard to bring to easy cultivation. I wish them luck though.
Oh, sorry about all my tatsoi/bok choy excitement. It’s just something new and different than the American standard veggies, greens, spinach and huge heads of whatever the standard cabbage is. Seems easier to grow too. Tatsoi has more vitamin C than oranges and loaded with vitamin A too. Even has a lot of protein for a veggie.
I have a good friend who is crazy for all the Asian Greens, so I hear about them on a regular basis.
She’s also stopped eating ‘meat’ except for Salmon for the health benefits, so I might have to break up with her after 45 years. ;)
