Train it up a trellis or let it trail from a shelf or hanging basket—Hoya australis ‘Waxvine’ brings a lush, tropical look with minimal fuss, making it a great pick for beginners and seasoned Hoya collectors alike.

Why You’ll Love Hoya australis

• Fragrant Blooms: Produces clusters (umbels) of porcelain-like, star-shaped flowers with a sweet scent.
• Glossy, Waxy Foliage: Thick leaves stay attractive year-round and help the plant tolerate occasional missed waterings.
• Easy & Adaptable: Does well in average indoor humidity and a range of bright-to-medium light conditions.
• Trailing or Climbing Habit: Ideal for hanging baskets, shelves, trellises, or moss poles.
• Pollinator Friendly (Outdoors): In its native habitat, flowers can attract pollinators—including butterflies.

Plant Profile

• Botanical Name: Hoya australis
• Common Names: Waxvine, Porcelain Flower, Honey Plant
• Family: Apocynaceae
• Native Range: Australia; parts of the South Pacific
• Growth Habit: Trailing / climbing vine
• Toxicity: Commonly listed as non-toxic, but as with any plant, discourage chewing and keep out of reach of pets/kids who like to nibble.

Care Guide

• Light: Best in bright, indirect light. Can tolerate medium light, but brighter light improves growth and blooming. Avoid intense, direct midday sun.
• Water: Let the top 1–2 inches of soil dry between waterings. Water thoroughly, then allow excess to drain. Overwatering is the fastest way to stress a Hoya.
• Humidity: Average home humidity is typically fine. Higher humidity can support faster growth and easier blooming, but it adapts well.
• Temperature: Prefers 60–85°F (16–29°C). Protect from cold drafts and sudden temperature drops.
• Soil: Use a chunky, well-draining mix (e.g., potting mix amended with orchid bark and perlite/pumice) to keep roots airy.
• Fertilizer: Feed monthly during spring/summer with a diluted balanced fertilizer. Reduce or pause feeding in fall/winter.
• Support: Provide a trellis or hoop if you want upward growth; Hoyas often bloom more readily on mature vines.

Propagation

Propagation is simple with stem cuttings. Take a cutting with 2–3 nodes, remove the lowest leaves, and root in water, sphagnum, or a chunky Hoya mix. Keep warm with bright, indirect light for best results.

Note: Avoid removing old flower spurs (peduncles)—Hoyas often rebloom from the same spurs.
