Hoya australis also know as the wax flower. Features a glossy green leaf. White flowers with pink. Native to Australia. This is a vine, does best in well drained soil but regular waterings. But don't keep it too dry or wet. Likes that good in between moisture. Can handle quite a bit of sun but keep out of the hot afternoon summer suns here in Missouri. This will stress the plant and turn foliage yellow. Plants need to be well established before peduncles will form.
