The listing, Brown Tomato Lot of 2 - Brownish Red & African Brown #10 - 20 seeds Each has ended.
1. Brownish Red Tomato - These are a 3rd generation grow out, of a tomato called African Brown.
I believe it might be a cross between 2nd generation African Brown, and a red tomato.
The original African Brown, was smaller, rounder, browner, with an indent on the blossom end.
Regardless, they're still edible.
So, there might be some variability in fruit color and shape.
These are great to grow out to eat, not so great for seed saving.
2. African Brown tomato - This is the parent to the Red Brown tomato, listed above. Because it's offspring varied, these seeds have the ability to cross. However, they should produce edible food good to eat, but saved seed, might produce variable results. 4th photo.
