This stephanotis was given to my parents for their wedding in 1961. It bloomed every year for my mom. After she passed in 2019 I took it home and did my best with it. But apparently these plants are notorious for being a bit fussy and resisted all my efforts to get it to flower. Two years ago I read something about how they don’t like being rotated, so I stopped doing that and bought a grow light to keep the non-sun side from going bald. That seems to have done the trick. There are about 5 or 6 clusters and this is the first to open up. And yes they smell fantastic!
It’s possible. In both my house and my mom’s, the plant was/is very close to a window, as close as possible. Mom’s was south facing, mine is west, but my window is twice as large as hers. (The top of both windows is about 1.5’ from the ceiling but the windowsill is higher on hers.)
