Tortuga, yup, you're correct, good eye. I got this small, grafted plant long time ago from the Greenscene plant sale here. It was labeled as Ugli, but it never had fruits that looked like it. I don't know what it is, but it doesn't taste that good, and fruits are always small.
One of these days, I wanted to graft a real Ugli scionwood from UCR/CCPP budwood but from reading some descriptions, it doesn't sound like a great tasting fruit. Have you tasted the Ugli fruit and is it worth me grafting a real scionwood?
I just have too many varieties now and not sure if I want to graft the Poorman's Grapefruit or Ugli on this small tree. My grafted tree has been in ground for over 10yrs and it is still only 6 ft tall with skinny branches like a key lime tree. I'm thinking of grafting more Kishu mandarins since they are very productive and fruits are sweet and seedless. I only have a small grafted Kishu so I might make this tree a dedicated (only one variety) Kishu.
