If the early ones don't have good flavor, I know in my heart you are right, not worth giving the space over to. Still, those first garden tomatoes after the long winter & spring are what I so look forward to. I didn't realize there were more than one variety of Mortgage Lifter, always something new to learn. I've never heard of Taxi tomato, I'll know to avoid it. I like yellow tomatoes, but my husband doesn't like anything except red tomatoes. Oddly, he didn't figure out that Purple Cherokee was anything except a dark red tomato, if I had told him the name he probably wouldn't have tried it.
