I'd like to offer my current hybrid wild Chiltepin / Reaper cross in its F3 condition as an interesting candidate. The plant seen here is now 6 1/2 months old and 8' 4" tall. The short one beside it was topped several times. Very prolific and currently setting thousands of pods that start verticle then turn down and ripen about 1" long. Is certainly a super hot and still has the Chiltepins way of little lasting burn. Makes great hot sauces. Does best in partial shade.
