Yes, definitely.
Even here in England we get a second bloom after a good summer, although the fruits remain tiny and usually drop off during the winter.
In fact, I've just been to look at my Poncirus, and found it still has about a dozen of these second bloom fruits. They're about 1cm across. So here's a picture of one twig:

Do you know the origin of your Poncirus with these leaves?


yes, I've bought this poncirus last spring in a nursery in Corsica. Usually,they use pomeroy seeds. I've bought five poncirus there, but only one has leaves like the picture (2).

I guess there is no way to know for sure without a DNA test, but, based on Ivica's pictures, I would think it is a pretty sure bet that he has a Poncirus. My next guess is, that when Ivica did his tasting, the ratio of poncirus juice to sugar and lemon was on the low side. I would also consider the fact that there is always a significant improvement in taste when you are sampling fruit you grew yourself. At least that is how it works at my house. Very Happy

Great pictures Ivica! Thanks!

The largest snow last season we got when mother plant was ready to flower. We had drought this summer. Mother plant's owner didn't feed or water that plant. Here is how it looks as of 2007-09-16:

This is Don from Oaklahoma City, Oaklahoma. He is a member of this forum, although Don does not post much. He has been delving into poncerious hybrids for a long time, in an effort to find a cold hardy citrus fruit, that will produce a quality fruit of good taste. An ardous task to be sure. Many say with a slim chance of success. - Millet

As a general rule, my poncirus will not reboom, but stress will induce many flowering plants to bloom out of season. Haven't I read that, in the past, citrus were purposely stressed, by withholding water, to provide out of season bloom for royalty? You know, come to think of it, I have one Flying Dragon hybrid that blooms several times early in the season. It will not set fruit on the first bloom.

Askhat, the leaves of your Poncirus looks similar to what I have here.

Just thinking about posibility that Granmother Tree is in Malinska (west coast of Krk Island, Croatia):

1. I gave 50% chance that Granmother Tree is/was grown there and not somewhere else.

2. Mother Tree was picked-up there 30 years ago, as 10 cm tall seedling.

3. Malinska is village oriented toward turism.

Satellite photos shows a lot of new houses/objects. That means alot of old backyards destroyed.

Road movie filmed by young talian people shows that some old backyards are still present.

Chance that Granma Tree is there is slim but maybe...

Does anyone know how long P. trifoliata tree can live ?
Or, how old is the oldest known PT tree ?
