RE: Blood Orange Juice
While this orange will grow in Florida, it is native to the Mediterranean... the southern region of Spain, if I remember correctly.
Although I've spent quite a bit of time in Florida, I can't recall ever having seen a blood orange. Grandpa Carlton didn't have any of those in his grove. I do know, though, that the juice and the pulp are almost bright red.
As an aside, there is a variety of orange named Lue Gim Gong after the man who developed it by cross-seeding trees existing in Florida with those of his native China. He lived just west of DeLand in Volusia County, and is buried in Oakdale Cemetery in DeLand. This orange still bears the name of this "Chinese Burbank," and it is now classed as a variety of Valencia. Grandpa Carlton had quite a few of those trees, which are still propogated today.
Orange you glad I told you that juicy tidbit?
