Hey Michael,
Those are good looking NuMex Heritage 6-4 Pepper Plants!
Mine, from the seeds you sent me are doing fine - - but far behind yours. Flowering now, but no growing fruitset. I've had a few that have dropped off the plant, which is a bit concerning:
I am also growing Joe E. Parker and Big Jim NuMex Peppers, to compare productivity and most important, taste. Unlike most other Pepper folks, I am looking for a somewhat mild NuMex to put on top hamburgers, etc. Will be fun to see which one best fits my taste profile.
