They also say, "A medium shrub, growing to 1.5m+ in size, they produce lobed leaves and small flowers in spring, followed by edible fruit in summer." Unless I got it really wrong, figs don't produce flowers, figs are the inverted flowers. I bet if you had an air layer you could get a plant to look like that, or even just sticking some branches into a pot for the photo (that's the cynic in me talking).
I've read, no practical experience, that bonsai plants can produce fruit, but can't remember if it will get full size. My one plant that fruited is still in a relatively small pot. I think I'll leave it in there and see if it will make full sized fruits again.
