I purchased a dwarf citrus reticulata Citura tangerine years ago. It flowered for the first time this spring and has fruit. I read some literature that said some tangerines are ripe when green others when orange, so I picked a tiny fruit that was half orange half green to test. It was juicy, full of flavor, and pucker-your-lips tart. My question is when do the sugars develop? What type of citrus is this, because I dont find any reputable information about a Citura variety? F.Y.I. the plant is in North Carolina. Our temps in October run about 49F to 79F.
