Late last season, I planted some seeds from my patio tomato plant. I kept it growing through the winter. There were several diebacks, times when it seemed done for, but new green growth always kept coming up from some part of the plant. Come spring, I put it out on the deck and watched it flower (as well as drop some flowers). The payoff finally came today when I picked a small, cracked but ruby red tomato off the plant. I sliced it up with some homegrown lettuce and had a homegrown salad. It may have been a small tomato (bigger than a cherry tomato, smaller than a plum tomato) but it had the rich ripe flavor that homegrown tomatoes are known for.
Best of all, there are more tomatoes coming on. I guess I'll have to save some of these seeds too.
