Ross, a few weeks ago I bought a Little Ruby on Ebay from Well Spring Gardens, along with several other fig plants. LR was about 4 inches in height upon arrival, and although small, healthy.
I repotted into a larger container, and LR seems to be growing already- I think she's already a beautiful little tree, although of course I can't tell you anything about the fruit at this point..
Initially i tried to order at least a few of the dwarf varieties because it's necessary to grow most of my trees in pots right now.
Interesting thread, and i'm also hoping to learn more about this variety.
