We had a cold snap in January and a hailstorm about a month ago, and my Stephanotis had shredded leaves and dead branches. While I was up the ladder cutting them out, I found two fruit! They look like elongated mangoes or avocadoes, not edible. I never knew that Stephanotis set fruit, but the internet tells me that they do this from time to time, although I was unable to find any conclusive information on why or what triggers it. I have cut one open and will leave the other to dry and then cut it open to see what happens. Apparently, they can be propagated from the seed.
