80-Days. Nairobi Nights tomato seeds were sent to me by my African friend. This is a very rich, balanced and delicious tomato that everyone should grow. For me, this is a complete tomato and it will always have a regular spot in my garden. There is some similarities to Black Trim, which is a good tomato, but I feel that Nairobi Nights is a far superior fruit. It seems to love hotter weather and just flourishes during the height of the season here. Add this one to your rotation of black tomatoes.
