Availability: • A number of vendors offer it, now (June 2020).
• It should be easy to get seeds if you're a member of Tomatoville and/or TomatoJunction.
I grew Girl Girl's Weird Thing in 2016. It grew nice-sized tomatoes and was more prolific and early than the average tomato that year. The tomatoes looked nice, but the color was slightly different and they lacked taste; so, I think mine was a cross: It's supposed to have good flavor. Whatever the case, I got a cross or mixed up seed from my 2016 saved seeds with similar, but more prolific, results, in 2017; it was supposed to be Missouri Pink Love Apple, which I also grew in 2016 (but it looked and tasted like GGWT had).
If I recall, in 2017, I also grew GGWT from seeds I saved in 2016, but it was crowded and shaded; it didn't produce.
I plan to grow it again from another seed source in 2021.
There was an old thread on Gardenweb about this, where Jessica Hughes posted, I believe, but I can't seem to find it, yet. I think they were discussing what to name the tomato.
