This chilli is just one the hottest chillies in the world, averaging at around a million Scoville Heat Units. Like all chillies, however its heat level is strongly influenced by growing conditions, there is no guarantee every crop will reach such an astronomical level. The scorching heat of the fruit is combined with a distinctive fruity aroma, making this a truly exceptional chilli. These wrinkled, wedge-shaped fruit ripen from green to red, and can be harvested at either stage of maturity. They can be up to 20 to 30 mm wide at the shoulders and 40 to 50 mm long, but can be smaller when the plants are grown in pots.The plants are tall and ungainly; when given plenty of light and grown in the ground – where root growth is unrestricted – they can reach 1.5 metres or more. When grown in pots, however, their height can be considerably reduced, with smaller pots producing small plants.
