I've been hoping for some type of hardy citrus but I don't think this is it.
When I was a kid farmers used it to keep animals out of their gardens but it kept getting out of hand. In the late 50's the state of Texas banned the use and sale of the stuff and ever since it has been destroyed as soon as it is found. I haven't seen one in at least 40 years in my part of Texas. It's a kind offer though. How come you have one? I thought they were an invasive plant every where and if not illegal at least banned since their roots have proven to be only partially successful as a rootstock. I could be wrong but I thought sour orange and trifoiliate orange were two different plants.
Our plants go back 20 years or so. These are in our woods and have zero sun across the decidious season but get sun in the winter. They all came from one plant that my EVE planted in the yard and I eventually killed it due to risk of a mowing accident. Now I am sure this is not the same story as is in the book of Genesis, but if the devil had ever formed a fruit with seeds I am fairly sure this hardy orange is not far from evil intent.
As I understand rootstocks the sour orange rootstock is the one used mostly today. The trifoilate was used but is not nemetode resistant and the fruit of the grafted tree was not completely satisfactory in some cultivars. But, as I understand, their rootstock is fairly good for tangerine/ mandarin types of oranges. So, why not dig them up and try to grow some type of tangerine from their roots.
it is a nasty plant once established
