I grow tomatoes in huge quantities because I can them for a year's worth of food for the family. I planted 170 plants this year all from my own collected seed. I have hybridized a Black Plum x Brandywine that I call Brandyplum which I have managed to grow true from seed for the past three years. Not long enough for me to 'brand' it but I love it. It has the potato leaf that the Brandywine has and produces a mahogany colored pleated fruit that has a fabulous flavor. I also grow some others from my saved seed but the Black Plum makes the best sauce/salsa in my humble opinion. What types do any of you gardeners grow, and why? I would love to know if any of you have done your own crosses too.
