I have read many posts in past about this subject- I have this plant, was sposed to go outside this spring, but was growing well, already getting tall, and it was very windy. Eventually it was moved to a spot it LOVES, and I guess it owns this window, now.
The window faces due north, I have pulled up the blinds as you can see to try and help. no direct sun EVER from that direction.
to the left are the very sunny and hot west windows. Unfortunately, it has been SO hot, that I close the blinds on that side from no later than 1 PM till around 6 or 7 PM.
you can see that this jasmine has set flowers.
I am worried about the canaries on the other end of the porch, ha ha! The scent is just RAVISHING after dark, I expect to hear little "plops" as they succumb and fall off their perches..
