Heart tomatoes and one called persimmon I grew one year.
The only reason I didn't grow it again was productivity
Maybe I should try again I really like it.
I remember making a hamburger with one the thing stuck out all the way around and the slice was about 1/2 inch thick.
One of the best burgers I have ever had.
They were huge.
