They were from my own plant. I only got 5 scorpions off of it this year. Very disappointing grow season for me this year!
Coincidentally that's 5 more scorpions than I got this year, having not planted any. Next year will be a different story, however.
My Scotch Bonnets aren't scotch bonnets, I discovered. They're some other kind of pepper (likely C. annuum) mislabeled and sold at Armstrong in Novato. Bleh.
Next year I'm going to try for REAL Scotch Bonnets or maybe make the mustard sauce again using fatalii or datil.
