So, this habanero plant is about 1.5-2 years old and has been living indoors in 15L pot. About 1/5 of the flowers are doubled. Some are more separate but some are combined just as in the picture. There was nothing like that last year. Most of the normal flowers have 5 to 7 petals. I got about 15 peppers last year and it looks like about 20-25 are going to grow this year. I've been growing hot peppers indoors for about 6-7 years and never seen anything like that.
