If you remember a vine creeping around your grandmother’s kitchen, chances are it was a Hoya plant. This tropical indoor plant — often called a “Wax plant” due to its thick waxy leaves — is a classic because it lives forever, grows to be enormous, and creates beautiful, porcelain-like fragrant flower clusters (it’s also often called “Porcelain flower”).
Hoya (family Asclepiadaceae) A genus of twining and root-climbing plants that have fleshy leaves and flowers which are waxy, highly fragrant, showy, and borne in umbels. They are delightful hothouse ornamentals. There are about 90 species, native from southern China to the Pacific.
The Hoya must be mature (3+ years old) in order to bloom! It will need bright diffused light at the very least, but as stated above, a bit of direct sun is beneficial. If age and light are on your side, you can also encourage flowers by keeping your Hoya in a snug pot and not disturbing the roots too much. And of course, don't cut those peduncles! Once in bloom, absolutely do not repot, mist the plant, or move it around often, or it will be more likely to drop it's blooms. Given the right conditions, your Hoya is likely to provide you with nectarous blooms year.
