Hoya australis, also known as the wax flower plant, is a species of flowering plant in the family Apocynaceae. It is native to Australia and grows as a climbing vine in its natural habitat, but it can also be grown as a hanging plant or trained to grow on a trellis or pole. Hoya australis is named for its waxy, fragrant flowers that bloom in clusters and range in color from white to pink. The leaves are glossy, leathery, and succulent, and they grow opposite each other on the stem. The plant prefers bright, indirect light and moderate watering, allowing the soil to dry out partially between waterings. It is a relatively easy plant to care for and is known for its air-purifying qualities. Hoya australis is a popular houseplant and is often grown for its attractive foliage and fragrant flowers.
