tcstoehr said: Interesting question but I don't know if it makes much sense or not. Heirloom vegetables are so-called because their seeds grew true to the parent and were kept in families from one generation to the next. Even smuggled into the US by immigrants who valued their genetics and predictable performance. I don't know if we have anything like this in semps. Maybe the original species plants? Since semps reproduce so easily from offsets rather than seeds the notion of "heirloom" might not apply.
