Found this strange fruit on my seven-year-old Stephanotis. Will wait the seven or so months it takes to ripen and propagate from them for swap!
You should plant them in moderately fertile, humus-rich, moist but well-drained soil with filtered sunlight as full sun will burn the flowers.
You can propagate from seeds in the spring or cuttings in the summer.
