I always like to use the University of Arizona as a resource because they provide research-based, non-biased horticultural information. They aren't a commercial enterprise and aren't trying to sell you something. The U of A has conducted field trials for citrus for decades. In the Phoenix area the citrus research farm is located in Waddell. Sadly, this facility will be closing soon as the land was leased and the term is up. (The remaining citrus research station is in Yuma.) Each January the U of A Extension office holds a Citrus Clinic where speakers from the University as well as local experts gather to pass along information to the public. In the east valley it is held at Greenfield Citrus Nursery and in the west valley at the research station in Waddell. Here's a link to information on publications from the U of A. Click on the link to Low Desert Citrus Varieties which includes five of the pigmented oranges. A good book on this subject is Citrus - Complete Guide to Selecting and Growing More Than 100 Varieties For Califoria, Arizona, Texas, The Gulf Coast and Florida by Lance Walheim, ISBN 0-9628236-4-3. Here is a link that might be useful: Low Desert Citrus Varieties

I would call that orange lightly pigmented. Although a beautiful and tasty fruit. I am a bit of a perfectionist. This is what a fully pigmented Moro will look like if done "correctly" This is the color I see with my Moros exposed to warm days and cold nights. These dark fruits taste different, a berry/wine flavor profile, very uniqie. I cant get enough of them.

Off the top of my head: Sanguinelli Blood, Tarocco, Moro, Budd Blood, Smith Red, Vaniglia Sanguigno, Valentine(Pumello), Red Vaencia, and Cara Cara (lycopene). I mighthave a couple more that I am not remembering and I have multiples of some and a few Moro and Tarocco from seed. I think they all have gotten fruitlets and several have developed mature fruit but they are all still small trees so not a huge amount of fruit yet. I was hoping for a lot of fruit this year as the trees have been doing well even after the greenhouse overheat in April, but something keeps eating or stealing the fruit when they get about 2 inches in diameter. It is quite frustrating. I never had problems other years so it must be something new to my yard. I have chipmunks for the first time this year, but the fruit seem to large for them to take. I had a second Tarocco, but it died suddenly for no reason I could ever figure out. It's twin is still doing fine and they were next to each other in the greenhouse when the one started dying almost overnight. I had a cocktail grapefruit/pumelo die like that also. I am wondering if that is a rootstock compatibility issue when that happens or maybe the graft fails. The Cocktail made 5 ripe fruit last winter and suddenly died overnight. It had fruited at least twice before that and was a strong grower. It was one of my largest trees. Again, I don't know why it died. It did not seem to be prone to scale, spider mites, aphids or other bugs. The rootstock still looks alive, but it has not sprouted at all. I have been waiting all summer. The Tarocco rootstock sprouted some kind of trifoliate and I now have a fairly large tree to graft onto when I get brave enough and find the time to try grafting. Some trees are real scale magnets,but these were not. Cory

LOL Brian and Maggy...Maggy...I am not sure. I think it must be nearing 50, but keep in mind that many are young. They will need to remain relatively small, unlike Brian's because I will not be able to get them in my house otherwise ;-). My oldest tree is about 7-8 years old and I've had him 4-5 years. Yes - they are either male or female and most have name tags with their variety and assigned name that my kids give them ;-). I even have one named after Vladimir since it's because of him mentioning the tree that I bought it. I may have to name the gold nugget after Brian...
