It is long-lived and can grow to long lengths if left untrimmed. Other names for this plant include Waxvine, Honey plant, and Porcelain Flower. The waxy flowers on this grow in late winter and last well throughout summer.

How to Care for the Plant

Water
Water moderately during the growing season, allowing the top layer of soil to dry out between watering. In their rest period (winter), water lightly to prevent the plant from drying out but don't overwater.
Pruning
For wax plants that are flowering, however, switch to a 5:10:3 with a high phosphorus number to encourage blooming. Use a high phosphate fertilizer for 2 months prior to the plant's normal blooming time. That will fuel the plant to produce more profuse and larger blooms.
Fertilizer
Allow flowers to fade and fall naturally without cutting or pinching off the short flower stems, called spurs or penducles.

Sunlight
Keeping in good light will help the Hoya plant to not only grow better but also prevents the soil from staying too damp.
Soil
Naturally epiphytic, so demands loose, well-draining potting mix. I prefer to use equal parts coco coir, perlite, and orchid bark, with about 10% worm castings to improve soil fertility.
Temperature
Does best in temperatures of 65 – 80°F (18 – 26°C). Avoid exposure to temperatures below 45°F (7°C).
