Prairie Fire

Specie: Capsicum annuum
Bears different color fruit, changing from white to purple to orange, to red.  Red Scoville units = 70,000-100,000

I've seen many different descriptors for this chili, but this is what it looks like.  Peppers go from white to red, while meandering through a rainbow of colors, including orange and purple.  The red peppers are the most mature and spiciest.
