120 days. Believed to be the hottest pepper in the world, the Carolina Reaper is a serious scorcher! For those extreme pepper eaters, Carolina Reaper is a must. For those less adventurous, they make a great conversation piece in the garden. These devious little peppers are fiery red with a little scythe shaped tail at the base of many fruit, hence the name reaper. The heat rating on these monsters can be over 1,500,000 Scovilles; in comparison the spicy habanero is a mere 100,000 Scovilles!
