I have a few. One is a small bush sized plant that I have in the ground with protection. It is a rooted cutting from a seedling grown from seed stock imported from Taiwan or Okinawa. The original bush lived for 3-4 years in the ground here in Raleigh before dying (I wasn't aware of it until after it died and I believe it died in the summer). Its leaves are not like the Yamamomo you see in photos online (a bit more serrated). We are having a very mild winter and yet it is still suffering. I think it will survive but there will be winter damage.

I have three potted grafted plants that came recently from Japan. One appears to have died, one is having a few problems but looks fine. The third one is doing great with a great deal of new growth. I have no idea what the rootstock is, it is sprouting leaves and they don't look like any sort of Myrica to me. These three are being wintered over in my simple hoophouse/greenhouse where I store my citrus and large tropicals.

They were legally imported by someone that was buying and importing trees for research (not fruit tree research). He was going to Japan and I casually mentioned that I was searching for named cultivars of Yamamomo and he said if the dealers he was working with had any he would pick them up for me and send them through USDA with his stuff. He surprised me with these three. He is also the person that gave me the rooted cutting from the seed grown tree a couple of years ago. He took a lot of cuttings to be back ups in case I kill any of the ones I bought. I haven't seen him in months and haven't heard how his plants are doing.

It took me five years to track down my first plant. I've ordered seeds from China in the past and none of them sprouted and I did every trick in the book.

These trees are common roadside trees in zone 7 Japan and China but they don't fruit much that far north. Prime fruit production is in the same zones that grow Satsuma citrus.

I assume the grafted ones are females and I hope the one in the ground is male.
