Ha, ha. I am an expert at 'finding' plants along the roadside and in dumpsters (with permission, of course) and bringing home NOID strays from local swaps. Sometimes it takes me 3 years to make an identification of a plant. Some examples: Musk Okra (Abelmoschus moschatus); Tung Tree (Aleurites fordii); Cinnamon Ginger (Alpinia nutans); Cashmere Bouquet (Clerodendrum bungei).
And just when I get it figured out someone changes the accepted botanical name; who can keep up?
Example: Aleurites fordii is now Vernicia fordii, or at least that's what Google tells me.
You are ahead of the game as your plant was growing in an established garden and is most likely, but not guaranteed to be, a food plant.
