Hoya australis

Hoya australis is a vigorous Australian species with broad, glossy green leaves and sturdy vining stems that climb readily when supported. The foliage develops a firm texture and clear veining, and mature plants produce rounded clusters of white flowers with a red centre. The blooms carry a sweet fragrance and are held neatly along the vines.

The plant grows strongly in bright filtered light with warm, stable temperatures and a lightly drying cycle. It adapts well to indoor environments, responding positively to regular feeding during the warmer months. Its reliable temperament and attractive foliage make it one of the most widely grown hoyas in Australia.
