We got our first ripe tomatoes, today. There were three altogether: one from the Galapagos Island plant from a seed from a fruit with 5 locules, and the other two were from the Galapagos Island tomato from seeds from fruits that had withstood several hard freezes.
I gave the fruits to someone, who ate them, and said they were good, and described them as tart.
The fruits started to color a day or two ago.
I think the one from the 5-chamber plant is on the right, but I could be wrong:
As you can see the one from the 5-chamber plant doesn't appear to have five chambers, by the fruit size and shape. Nevertheless, I am pleased with the fruits. They're a nice color.
