Other names: Waxvine

What is the plant

Let this vine spread through any space, and it will dazzle with its unique waxy flowers that drip in nectar and attract beautiful companions.

Also known as Waxvine, this evergreen vining plant is native to Australia.
It has shiny succulent and thick oval-shaped leaves, whose color depends on the amount of sun the plant receives. This means sunnier environments create brighter, greener leaves, and shade creates dark green leaves.

It bears small fragrant flowers with marked red lobes, arranged in umbrella-shaped clusters and with five waxy triangular petals. These are the traits that allow for better identification. It can bloom at any point of the year, and even when not in bloom, it has long, elegant attractive stems. It’s easy to care for, air-purifying and can grow around 13-33 feet (4-10 m).

How to Care for the Plant

Water
Common Waxflower enjoys humidity and should be watered only when the soil is dry. Reduce watering frequency in fall and winter. Overwatering and underwatering are both equally harmful to it since it is not drought tolerant and prone to rot.
Pruning
Pruning is required to control the size and should be done at least once a year to promote a compact look.
Fertilizer
Feed Hoya australis once or twice during spring.

Sunlight
Light allows for better flowering, so this plant enjoys plenty of indirect light. Direct sunlight can be beneficial too, if not too intense, as it can cause damage. It can also be grown in shadier conditions, but it won’t bloom. It can be supplemented with artificial growing lights.
Soil
Choose well-drained soil that is still able to retain some moisture.
Propagation
By cuttings, which are dipped in root hormones.
