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!
I had one of these. My mother in law gave it to me a couple of years before I married my wife. She said it hadn't bloomed for _ long time _ years and it only blooms when there is love in the house. I don't think she thought it would bloom but it had clumps of flowers in a couple of months. I think it just needed more light.
