Adriano they get some red round circles/spots on the rime but they are pink/redish on the inside and sweet usually by Feb. have eating them up will try to remember to take photo of picked fruit... I pick and eat forgetting about the photos will try to do better. I guess I'm still in my happy/excited phase....there r a few people in my area that have lemon and navel trees. One family has 2 trees that they say is Valencia that came from Florida. The leaves r small like the mandarian and taste consist of lime, lemon and grapefruit. The fruit is yellow, size of a navel orange, rime thick like grapefruit, and tart. I think it is an Yuzu.....from reading and seeing pics....can someone help....don't have any photo of this tree. After hearing about it I had to see it. Tree about 20 ft wing span 15 to 20, turnk as several shoots close to the ground, and has surived some cold winters as low as 7 degrees. A week before I saw these 2 tree I got some damage on my uncovered trees. This tree green as money.....lol....with no damage.
