I got some fruit at a fruit stand in Colombia and planted the seeds.
One is definitely Lulo (Solanum quitoense).
The other one, pictured below, with my extremely limited Spanish, I thought the vendor told me was Cocona ( I even had her write it down to make sure).
The Lulo thrived, but the Cocona plants died, so when I started looking for replacement seeds, nothing looked like what I had brought back.
So is this some sort of weird purple Cocona (Solanum sessiliflorum), or something else? The fruit was about two inches across and smooth. The leaves of the plant were large, and looked very similar to the Lulo leaves, without the purple spines.
I would love to find seeds of the purple fleshed variety, as it was very creamy and tasty!
Thanks! Carolyn
