Citrus tree identification
So IÃÂ´ve planted som citrus seeds over the previous years, and some of the trees have died and some have thrived beautifully. The thing is, I donÃÂ´t know what species some of them are and this one in the picture especially. I would like to plant some more trees, but of different varieties so as to, hopefully, get different fruits from them some years from now. Can anyone help me identify this one? If the picture of the leaves is not enough information to go on to identify the variety, then please let me know, and I will try to get it for you. I think what I have planted during the years are: orange, lemon, grapefruit, blood orange, lime and some kind of mandarin or clementine.
Any help is much appreciated :)
