I have only had this experience with one other plant.This is the 2nd. summer 1 of my Hoya's has had seed pods.Last year the pods started in the summer and just grew larger until this summer,growing an entire year and i miss it opening and the seeds blew away,it only had 2 pods.This year now that i know what it is, i will pay more attention next summer.
How long approximately does it take for these pods to mature? They are about a month & a half or more old.They are soft and easily bent.I also assume the strong sun is the cause of the red color on the pods,the color is only on the top where the sun is the strongest.
