Despite the best efforts of out typical St. Louis weather, my peppers are producing quite nicely. However, I took a peek at my japalenos yesterday, and they have dark skin on the sunward side of the fruit. Is this typical (sunburn?), or is something awry (disease)? We've gotten a good amount of rain lately and we had a bit of a cool spell (50s at night), but no other peppers have this funky eggplant look. Thanks, Steve
