Just read some disturbing info at http://plantanswers.tamu.edu/vegetables/pepper.html regarding pepper plants.
Peppers, like tomatoes, are sensitive to temperature. Most peppers will drop their blooms when daytime temperatures get much above 90 degrees F. in combination with night temperatures above 75 degrees F.
Hmm, that doesn’t bode well for Central Texas, where temps get well into the 90s and above during summer (see average Austin temeratures). They did mention that jalapenos fare a bit better than other peppers. We’ll see.
