Fang Liu, I have two young native myricas (myrica californica) in the ground but I thought you said myrica cerifera had been more successful rootstock for the yang mei. If you want to "adopt" one of my myrica and try grafting it, that would be fine. It's in the front yard so you could come visit your child anytime. I'm two miles from the ocean, so it is definitely more humid here than in Burbank. If you're going to be at the WLA CRFG scion exchange, we can talk then. BTW, if you want a myrica californica for your very own, the Grow Native Nursery in the WLA VA grounds currently has five one-gallon trees. I got mine from them as one-gallons several months ago, upcanned them to five gallons and put them in the ground last week. Though of course, I am still hoping to bring back genuine yang mei trees next month.
