How tall and wide is it and is it fragrant? If fragrant, then perhaps Fragrant Cloud.

Yes, but most citrus grow true-to-type from seed due to Nucellar embryony... certainly most oranges and grapefruit. Exceptions are Meyer lemon, 'Temple' oranges, Clementines, Persian lime, most pummelos, I think. Tangors and Tangelos put off a high % of nucellar seedlings. According to my notes where I keep my citrus information, I had this filed away. This is a quote from Dr. Malcolm Manners, professor of Citrus Science at Florida Southern College: 'Nearly all of the sweet oranges (C. sinensis) come true-to type from seed. A few (some navels, 'Pineapple') make minor variations in their seedlings, even though they are technically nucellar. Nearly all grapefruit also come true-to-type. The only exception I can think of is 'Thompson Pink' which produces 'Marsh Seedless' seedlings, since it is a periclinal chimera, and the mutant tissue is not in the layer that makes the seeds. The vast majority of mandarin types are also nucellar, and therefore, come true-to-type. Also, nearly all lemons, 'Key' Lime, and most other sour-fruited types come true. Persian limes do not. Meyer is monoembryonic, so does not come true-to-type from seed. Actually, the list of citrus that don't come true is quite small.'

impossible to really know, but if i had to guess, it definitely looks like a dwarf plant.. which would be the tiny tim.

Sunshine, it's nice that you can grow all of those citrus trees in your planting zone. I'm glad you have a Valencia orange. I used to have one that bore nice fruit for me for a couple of seasons until citrus greening hit us here. That was many years back. The tree is not doing anything now except hanging onto dear life. Other citrus trees that are doing well for me are all my lemons. I also have a couple of Bearss Lemons. They are very heavy producers and now my branches are loaded with fruit almost ready for harvest. I also have a few of the Keiffer Lime. I thought they were very cold sensitive, but it turned out they really weren't affected too much by our Winter here, so I had one of the planted in the ground. It really took off and it's now standing at 10-12ft height.
