I plant two kinds of heirloon plants, they grow to a height of 8 feet, under the right conditions 10 feet plus. The seeds came from Italy, I have no idea what there called.
One plant has traditional tomatoes, very large about 1 pound each, the other is a plum type but huge double the size of an avocado, very sweet all meat hardly any seeds, only about 10 each.
I've have about 20 of each and and a few cherry tomato plants.
