The Mustard Habanero Pepper starts out as very light green blushed with purple, and ripen to a unique mustard color and finally to fiery orange, with plants bearing fruits of all colors simultaneously. Originated in the fields of James Weaver, Kutztown, Pennsylvania, where it appeared as an off-type of some more conventional variety. James grew out seed he collected, and the result is a stable and very singular new variety. Super hot, like most habaneros.
The chile "heat" of the Mustard Habanero typically ranges from 100,000 to 350,000 on the Scoville scale.
