Brandywine is one of the favorite varieties that I plant every year along with the early girl and couple other beefsteak varieties: Big Beef, Parks Whooper. One of the grape tomatoes that both my wife and I like is the "Santa" variety. You can't buy the seeds in a packet, but you can buy the tomatoes in the supermarket and save a few seeds from one. They seem to grow true and are very sweet, not as prolific or as fast growing as the super sweet 100s but they’re better yet fresh and vine ripened.
Does anyone have a good hearty roma variety? Last two years I've planted the "Roma", but they seem to get diseased and dye off too early.
