I don't know if you are familiar with these peppers - commonly sold in bottles or at deli's. The peppers, orange when ripe, are sweet and uniquely tasty. The seeds are patented and its extremely difficult to get hold of them, even plants are rare.
I got some seeds from family in Zimbabwe and planted a few. Unfortunately our season is too short but the good news is that the plants are perennial, the bad news is that they are relatively huge ! I have had to bring mine indoors. Its covered in fruit - I just hope that it can make it through Winter on reduced sunlight.
Plants are at least 3 feet tall.
