    As Citrus trifoliata is ‘naturalized’ in the American southeast, what is it’s native range?

    I have two of the Flying Dragon cultivar. They both survived -17F this past winter and the larger of the two flowered.
    I’ve made marmalade out of the fruits and it is edible but not a favorite! The rind also has a gummy substance when cut that sticks to everything and can only be removed with nail polish or the like.

    Citrus trifoliate is of Chinese origin . As per patches in the South East , spent many an hour hunting deer and turkey in Florida in my younger days and never saw a volunteer patch . Granted they will from large patches from trees that are planted as for some strange reason there is no parental alleopathy to their own seedlings , this is rare as most woody plants eschew they own offspring . I have seen Citrus sinensis become a little invasive but never to the point of establishing patches of resistance . Somehow I think the point of it being invasive is a bit exaggerated , Citrus has been in production the parts of Fl, TX and LA for over 100 years and presumeably many homestead would have had trees of some sort or another , considering that C. trifoliate does not freeze would suggest that what is taking place is patches derived from old rootstocks that have resprouted after the chosen graft was frozen out . It should be remembered that C. trifoliate has recalcitrant seeds and have a very short life span and will quickly degrade and die upon exposure to the elements if ideal conditions are not available .

    I have managed to root several P. trifoliate suckers from rootstock from potted limes and lemons. It is fairly easy to root. It can then be used for rootstock if you want to try your hand at grafting.

    I was first introduced to this plant as a proposed hedge around military bases. It was given the common name “pain and terror.”

    Mystery solved! Or at least I’m now closer to the explanation of a mystery. I had a potted citrus that eventually died. I hauled it, pot and all, to the unheated garage until I could discard it in the spring and repurpose the pot. It must have experienced temps of close to zero on occasion repeatedly through the months of January and February. But in the spring green shoots came up from the soil line. I kept one shoot and trained it to a six-foot standard. It is probably a Citrus trifoliata. Thanks for the information.

    ” …flowers…have a typical citrus smell.” Really? I have read this in many sources yet I have never smelled much of anything from the many trees I have sampled.
