They are most likely hard because they harvested them green and then gassed them with ethylene to produce the red color. That helps them to ship better being the consistency of a tennis ball.seedcorn said:If it's the same variety they grow commercially here for Campbell's soup, V8, etc, expect them to be hard as tennis balls. I've seen them fall of semi's here on the highway and the tomato just roll like a ball. They are hard little things.
Don't know about the taste but you don't hear of anyone going out and robbing the tomatoes.
TGS has Heartland listed as a dwarf hybrid. Sounds interesting . . .old fashioned said:. . . I also picked up starts of "heartland" that grew wonderful, good taste, plant stayed fairly compact with almost no sprawl until much later near harvest time-then kinda flopped all over. I don't know if it's an heirloom type or hybrid-probably hybrid. If anyone knows I'd love to hear cause if heirloom I want to grow them again. . .
