Wax Vine Hoya

Wax vine is a genus of over 550 species of epiphytic, climbing, evergreen herbaceous perennials from tropical and subtropical regions of Asia and islands of the western Pacific. It is a member of the Dogbane family (Apocynaceae). The genus name commemorates Thomas Hoy, the 18th-century gardener to the Duke of Northumberland.

Hoyas are popular houseplants, and most are easy to grow and tolerant of a wide range of conditions. As they are epiphytes in nature, they need a free-draining, organic potting mix that dries out between watering. They are intolerant of a soggy potting mix and wet roots. The plants grow better when supported by a trellis or pole, over which the stems can be trained. Most species need bright light, dappled shade, or full morning sun. They do not need full sun all day. They are frost intolerant and must be grown as houseplants or greenhouse plants. 

Wax plants, so named for their thick, waxy leaves, have both ornamental foliage and attractive flowers. Some species are shy to flower but have attractive foliage. Many species have variegated cultivars. Flowers are often fragrant. Most species are easily propagated by stem cuttings.

Hoyas can be grown as specimen plants or as hanging basket plants.
