Now I'm sort of confused! I'm no jasmine expert
This is my Confederate Jasmine, growing for many years on a pole that at one point had a bird house at the top of it, it's a very dark green (like yours), and here is a picture of it's blooms. Like Big Bill, mine also blooms in May...I have never fertilized it and I do not water it...it just grows and blooms all on it's own, but it IS in full sun for MOST of the day:
This is what I know as Star Jasmine, and it's bloom as well (the flowers, and leaves are quite different from the Confederate jasmine, and even the 'stems' are different, harder and not quite as vine-y as the Confederate) It has covered a lattice panes, is not far from my Confederate, so is also in sun most of the day and again, I do not water or fertilize:
Maybe
@Calif_Sue can shed some more light?
I'm sorry, I guess I'm not much help for your original question
@themonarchkey...
