I have an ornamental pepper from seed started last year. The peppers start purple, then turn red, eventually wrinkling when mature. I have peppers I cross pollinated that were still maturing as cold weather came so I had to bring the plant inside. The peppers were purple and suddenly started getting red but then wrinkled halfway and a month later haven't fully reddened. I am not sure if they are ripe to pick as I need their seeds fertile. Perhaps the inside environment affected the color?
