Usually once every one to two years I will get a seedpod on a Hoya with the exception of Hoya papaschonii, which has them continually. Last year it was Hoya bella that got the pod and a year or two before that it was Hoya manipurensis. This seedpod shown below turned up virtually over night, and is growing at a rate of one inch per day on Hoya ruthiae. I know this is really rare, because in the book A Guide To Hoyas of Borneo it says that fruits are unknown. If fruits have not been spotted in the wild, then it is a rarity indeed and will really be fun to watch develop.
