Ohnivec Chilli grown 2021. Ohnivec Description from Real Seeds This is undoubtedly the biggest hot chilli we have ever had - loaded with fruit, almost a foot long and 2 inches wide, starting out a wonderful pale yellow, and ripening through orange to red. They are completely mild when yellow, but don't say we didn't warn you - they really are extremely hot once ripened to orange. Control the heat by picking them at the colour you prefer. The plants are about 2ft tall and 18 inches wide.
