This Hoya species comes from the Philippines and is quite rare in the wild. It flowers regularly throughout the year with umbels of about 10-15 flowers, but they are not scented. The plant is easy to propagate by cuttings and can flower the following year. It is an ideal hanging plant, but does need to be kept in the shade. Ordinary room temperature is fine and it can take a lot of water, especially when it is warm. In my greenhouse, a lot of hoyas get pollinated by moths, but I have not seen that on this species. The ones that do get pollinated by the moths tend to have a lot of white in the flower. White flowers usually indicate scent, so presumably that is what attracts the moths? Any thoughts anyone?
