Yeah, there is a Porter "Improved."
Sure. I had her tomato in my garden ... before we moved to this home in '95 and grow it every year. Uncle Marvin is gone now. His granddaughter told me that her mother grows that tomato.
I think as much about him as her when I sow the seeds. Also, I'm pleased how true they are. The flowers must self-pollinate in a very controlled way.
I'm not dogmatic about it or most any variety. However, I am sentimental. Those 2 tendencies are probably too strongly related to pretend otherwise

. Okay, Marvin was sentimental
and dogmatic. Ha! Ya know, you can get a little competitive with younger uncles ...
Anyway, it's like I was gifted with a couple of tomato varieties that turned out to
not be what they were supposed to be. A cross in the gardeners' tomato patch might be suspected. They really have more importance to me than if they had been exactly what others elsewhere are growing. Hey, I've got something unique!
Since I like tomatoes, it's not very likely that I would be disappointed. Now, I'm stuck with these things! Neither of my kids have shown much interest in gardening. I'm not sure how much interest they might have in family heirlooms. Hard to say, my son recently showed up with one of my jackets. He had picked it up at my father's home. It was a jacket that I wore when I was 4 years old!!!! At 4, I might have been interested in gardens but I'd never even seen a television.
