Description

Hoya curtisii is an epiphytic and lithophytic climber from the wet tropics of Thailand, Peninsula Malaysia, Borneo, and the Philippines. The species epithet honors Charles Curtis (1852–1928), plant explorer and Superintendent of Gardens and Forests, Penang, Malaysia. It is a member of the dogbane family (Apocynaceae).

The Porcelain Flower is a slow-growing, small, clinging vine with a climbing or cascading habit that grows up to 2 or 3 inches tall and 1 to 3 feet long. It has decorative leaves and very delicate, sweet-smelling flowers. The leaves are small, spade-shaped, waxy, and dark green with greenish-silvery variegations. The flowers are star-shaped clusters of 6 to 10 blooms of pink or red with a white center. Peduncles (the stalks that hold the flowers) are green and up to 2 inches long.

The plant prefers bright, indirect light for a least 6 hours per day, but direct sunlight should be avoided since it will scorch the leaves. This plant is drought tolerant and is very sensitive to overwatering. It prefers to dry out between thorough waterings. The potting mix should be a well-drained mixture of rich organic matter with a slightly acidic pH. Consider adding perlite or vermiculite to a commercial houseplant mix to aerate the mix and prevent drainage problems. The recommended temperature ranges between 60 and 80 degrees Fahrenheit to facilitate growth. Humidity levels between 50 and 60% are recommended. A humidifier may be needed to maintain adequate room moisture levels. Repotting is recommended every 2 or 3 years. To encourage blooming these plants prefer to be somewhat rootbound. Prune to remove dead or leggy vines and to encourage new growth. Take care not to prune off the peduncles, as the plant reblooms from the same peduncles for several years.

This plant is easy to grow and is low maintenance. It is a perfect vining plant for beginner gardeners. It can be grown cascading from a hanging basket or climbing on a moss pole in a container.

Insects, Diseases, and Other Plant Problems:  Insects affecting this plant include aphids, spider mites, scale and mealybugs. If the container does not keep the plant root-bound, it may hold excess water, which can lead to root rot. Overwatering and poor drainage will also result in root rot.
