not sure if anyone else has noticed this with their plant but it seems like as time goes on the flowers become more and more fragrant. and i must say i am LOVING it!
Yep, mine do the same. The fragrance seems to max out after the flower has been open 2 or 3 days. I've got five flowers open right now and the fragrance is unbelievably strong, almost too much! I love this plant, a real easy grower.
