Phonetic Spelling:HOY-ah kar-NO-suh

Genus:Hoya

Species:carnosa

Family:Asclepiadaceae

The porcelain flower, also known as the wax plant, is a popular choice for indoor gardening. This plant features long, slender vines adorned with glossy, deep green leaves that have a leathery texture, occasionally highlighted with silver or creamy white speckles. To enhance its fullness, you can wrap the sparsely leafed stems around a bamboo trellis and secure them using florist tape or strips of nylon stockings. It thrives best in bright, indirect light throughout the year. Be sure to let the soil dry out between waterings, as wax plants prefer high humidity; misting the leaves will help them flourish. The flowers are star-shaped and grow in clusters resembling parachutes, emitting a sweet fragrance and sometimes producing a sticky sap.
