Why cherries tomatoes different from other tomatoes?
The seed was actually growing inside of between fence. I believed the bird might have brought the seed here or perhaps, the wind. The plant grew wildly and branches have plenty of clusters fruits. Very juicy, sweet, & tender. The branches are tough & live quite a while like two years. It is cold-resistant and still bearing fruits during winter except below 45 -50 degrees Fahrenheit. The fruits & leaves are healthy. In my opinion, it is like an heirloom tomato plant.
