Found this variety last year. I was unable to find it then, but I would still like to have it.
However, as I live in the EU I can't easily get plants from Asia or the US where it seems to exist. But if anyone have seeds or have a plant in Europe they can consider parting with I would be very happy.

Do you graft?

To be honest I've never tried so I don't know what would be suitable to graft on or what the result will be. But I'm willing to learn.

So learn how to graft and tell me when you are ready.

I have shikuwasa on my list so it must be some where in my jungle.
You must know that they come from seed. It could take few years to give fruits.
