NuMex Twilight refer to one of the hottest chili peppers in the world beside Bhut Jolokia, Red Scotch Bonnet, Tabasco, etc. Aside from being very, very hot, the NuMex Twilight chilli peppers are also some of the most visually striking in the world. These peppers are about one inch long and very glossy and change color as they mature, from purple to orange to bright red. A NuMex Twilight plant covered with peppers in different stages of maturation is truly a sight.
