I have purchased a Tiger orange tree to grow indoors. In the public orangeries they really stand out with their variegated leaves and striped fruit. I'm pretty sure this must be the species, but does anyone know the cultivar? The answer is probably proprietary.

Well, as far as citrus goes.. I have rather mixed feelings on this particular variety. There are four established and growing in the backyard currently. As with all citrus, you have the constant cleanup duty of collecting and trashing rotten fruit from the yard and running off strangers who hop the fence to collect your oranges. And all of the trees I've got tend to taste somewhat bitter and produce a good deal of damaged fruit (could probably be corrected with proper fertilization and treatment). On the plus side, however, it's a darn hardy tree and has survived hurricanes and other foul weather without much disturbance. And the fruit does make a decent orange juice if mildly sweetened. Also pretty good for inclusion in sauces. =)
