For Karen and nan
Karen,yes,I know that there are many places that got Spoon,no doubt,from Park seeds initially, as I did myself,or elsewhere but it's still a tiny red currant tomato, Lycopersicon pimpinellifolium.
Nan,yes,originally it was from South America, all 14-15 species of Lycopersicon were from there.
Lots of wild red currant ones were spread by Spanish missionaries from Mexico along the Gulf Coast.
I think this link will help a lot.

Carolyn,who does think,as she noted in her first link that perhaps some might consider growing Sara's Galapagos since red currant ones did go from S America to the Galapagos islands.
