So, this year I left the fruit on my ichangensis IVIA until it became soft because on my recent trip (december 22) to Eisenhut I saw their mother plant and it was bearing a few fruit that were ginormous, at least compared to mine:
The fruit was already post maturity and very soft. I had read before that this cultivar had
sweetish rind (!). The nursery owner wouldn't let me have the plant (since it was the mother plant) so I took a nibble when he wasn't looking
.
Well, the rind was sweet indeed!
I thought perhaps if I left the fruit on my tree long enough, its rind would become sweetish too but it didn't. In fact, it is horrible. I can't really describe the taste but it is bitter and kerosene-like. I must be doing something wrong. My plant is still potted but so is the mother plant at Eisenhut.. Anyways, here are some pics of the fruit from my tree:
It was seedless once again.. Although the rind is horrible I am still quite satisfied. It looks like a useable lemon juice source for my climate. The pulp is acid like described above, the albedo has no flavour (but also no bitterness). Here's hoping it becomes as brilliant as the mother plant in the future.. I will certainly contact the nursery and inquire about how they actually care for theirs.
