Heat and Sun Tolerant Blotch

I've been keeping an "eye" on this new 2016 seedling while it has continued to develop outside the greenhouse this summer into something interesting.  It is exhibiting one of the best heat tolerant blotches that I have seen.  An added bonus is that it seems quite floriferous. 

The photo below was taken yesterday on the eleventh consecutive day where the temperature achieved 100ºF, or hotter, with nighttime temperatures in the 70's to 80's range during the period.

The photos directly below are of the same seedling taken on June 20th when the temperature reached 110ºF.  However, since on the week prior we had had nighttime temperatures down into the mid 60's, I was uncertain whether the blotch would continue to do well after an extended period of very warm nighttime and daytime temperatures.  I now have the answer!
