Years and years ago, the very first two fig trees I bought from a now defunct nursery that at the time was quite prestigious, were labled as "Brown Turkey" and "Black Mission". I knew nothing about figs at the time, other than that I wanted a couple.
They turned out to be Green Ischia and Magnolia. The GI was a very happy discovery, the Magnolia, not.
Just as recently I discovered the pitfalls of buying from Houston Patio and Garden. Wanted a dwarf nectarine to grow in a container and bought one a couple years ago and labled as a dwarf nectarine variety. Oh, it's a dwarf alright... a dwarf PEACH. Nice, fuzzy little fruit. Oh well, at least it's fruit, right?
There just seems to be more misinformation about figs, and the labeling at the big retailers seems to be more often than not incorrect.
