Why bother with having a tree in your backyard that grows just oranges, or just lemons, when you can have one tree that simultaneously grows peaches, apricots, plums, and nectarines or oranges, mandarins, lemons, limes, tangellos, grapefruit, and pomellos? What you need is a Fruit Salad Tree from the
Fruit Salad Tree Company. My wife insists these have to be a joke, arguing that everyone would already have a fruit salad tree if they were really possible to buy. I, on the other hand, think they're real... maybe because I don't know much about botany. But I figure they're just grafting different types of trees together. (via

Is there special care needed for multi-graft trees?
In horticultural practice, nearly all of these fruits are routinely grown on grafted rootstocks in commercial orchards. To graft plants, you take a "slip" (stem or twig cutting) and slice the cut end in a narrow wedge to expose the vascular tissue (what you might call its "veins." You then slice into a stub of rootstock to expose its vascular tissue. The slip is inserted into the rootstock, and usually tied together with a bit of tape or string to ensure that the tissues remain in contact. Over time, if the graft is kept clean and is done properly, the tissues meld together and scar tissue forms and the root and the slip become "one."
The rootstock is chosen from a related species to the slip. The rootstock often is chosen to provide certain qualities or characteristics to the plant. For example, in the USA, "wild orange" rootstock lends cold-hardiness to citrus, making it possible to grow oranges in areas that receive occasional freezing temperatures. Left to grow on its own, the wild orange rootstock bears bitter or sour oranges which are inedible as dessert fruit. Thus, sweet oranges, which are less cold hardy, are grafted onto the rootstock to offer the best of both worlds.
The plants offered by this nursery are simply rootstocks onto which several grafts have been made, each graft being of a different type of fruit.
I have personal knowledge that a tree bearing 5 types of citrus fruit is possible, because in my college horticulture class I grafted 5 types of citrus fruit onto a citrus rootstock as a lab assignment.
My grandfather was very proud of a camellia in his garden that had been grafted to bloom in 3 colors: red, white, and red-white streaked blossoms.
Whether the trees that are offered will really bear all 5 kinds of fruit is debatable. Limes and grapefruits have slightly different optimal growing conditions. Arguably, it would be difficult to provide one plant with the conditions conducive to fruit production for all 5 fruits (water, fertilizer, temperature, seasonal sun variations, etc.) Also, some grafts tend to grow more vigorously than others and over time one or more grafts may die off, leaving only 2 or 3 living grafts that might bear fruit.
The verdict on this? Botanically, not a hoax at all. As a gimmick or conversation starter, one of these trees would be kind of cute. However, as a real way of cultivating fruit for use in a fruit salad, it is probably not optimal.
Also, whenever
You can order directly from the company:

Or you can order from this website (cheaper), but these are only the plumb/nectarine/peach/tangerine varieties, no citrus that I could find.. good price though: http://www.gardenerschoice.net/index.asp?PageAction=VIEWPROD&ProdID=53
I think you can also find them from sellers on eBay...
It is surprising to me that these trees are not more popular, there are some in and around the Emmaville area, but they haven't seemed to spread far, perhaps more advertising is needed.

It is possible that the rootstock has overtaken the grafts, that the many branches you say have sprouted are rootstock growth. You can tell this by looking at the leaves, if they are tri lobed, then I am afraid to say they are rootstock.
We have a small op of multi graft citrus in QLD, Aus.Due 2 disease outbreaks we can only send our trees within our own state,without $$ quarantine measures.Check where U can send plants,B4 outlaying resources.Grow UR own rootstock,cheap+easy,research varieties 4 attributes.Graft varieties with similar growth rates(eg we find that Lisbon lemon is 2 vigourous for many other varieties and quickly "takes over".Prune back varieties which have shot until all your buds have taken.Continue to monitor balance,prune where necessary.Remove all rootstock growth from below + in between grafts.The 2 important things are prune to balance, + removal of rootstock growth.The internet is an invaluable source of info,use it 4 grafting techniques,rootstock+budwood variety info.Good luck,HELP DISPELL THIS MYTH that fruit salad trees do not work 😊
