I’ve seen this spelled as ‘Constoluto Genevese’ and ‘Costoluto Genovese’. When I purchased it the package was marked ‘Costoluto’ without the extra ‘n’ and I’ve been going by that since. It’s an old Italian variety so anyone who speaks Italian would have a better idea of the true name.
I actually took this photo in August 2006 but as my tomatoes form on the vines and anticipation mounts, I can’t help digging up a photo to remind me of what’s to come.
2006 was the only year I grew this pumpkin shaped heirloom, not because it was a dud but simply because the maximum number of tomatoes I can grow within a season is limited by space, leaving only a select few to make it back for a second or third year. I grew this indeterminate in a BIG container although the yield was still fairly low. The plant can produce fairly large fruit making it a better choice for in-ground gardens.
