Cara Cara Red Navel
Thanks everybody for the suggestions.
When I went to the nursery, they had Red Navels so thing Cara Cara and Red Navel are the same I got the Red Navel. I will plant it in the ground in the morning.
It is going to work out because my Satsuma had out grown its winter shelter so I will move it to the Red and build a bigger one for the Satsuma come fall.
