Interesting! I actually have Solanum aethiopicum and the burbank hybrid. In fact, I just planted a few of the burbanks...once I realized they aren't so sweet, I decided just to add a few to make into (sweetened) jams when fully ripe. The African eggplant aka Garden Egg (Solanum aethiopicum ) is the one I was referring to in my earlier post. Synonyms include Solanum gilo Raddi, Solanum olivare and Solanum pierreanum. Regarding pepinos, i waster tempted to grow these once I learned they are such heavy feeders. But that did not prove to translate into heavy nutritional content - very watery - so I left them alone.
