Unknown fig tree i think, its in California on ebay thats 20 seasons old for pickup only , you probably have to dig it out or at least cut around the roots to remove it but it will be fine after a while. Usually these dont bring a high price because no one really bothers , there was one in illinois that someone had for pickup i believe never sold.
So if you live perhaps nearby maybe it would be worth it who knows the figs seem to be dark type and tree looks healthy as well here is link for those interested or just want to look at it on ebay. If you do purchase it plaese post your experience here as its always nice to read .   ; )

It looks like maybe a mission. My only concern would be that it is full of nematodes. I am currently working in that area, so my interest is piqued.

Too far for me to pick up so I have a question related to "the trunk is at 45 degree". Next year I am going to plant a couple of potted trees at 30~45 degrees (recalling the Japanese plantation with horizontal trunks). Can someone predicts the pros and cons?

It is almost like spur pruning of grape vines. Good for those blessed with more horizontal space.
I guess the cages around the plants shown in the URL provided is for covering with plastic sheets during growing season. Is it?
