Hoya Macgillivrayi red (From surrisa) 6390

🌿 Hoya macgillivrayi is a legendary, large-growing epiphytic climbing wax plant in the Apocynaceae family, endemic to the remote Cape York Peninsula of northeastern Queensland, Australia. In its native habitat, it scales monsoon rainforest trees along riverbanks in the Iron and McIlwraith Ranges, climbing into the sunny upper canopy. It is an intermediate-level houseplant celebrated by horticulturists worldwide as the undisputed 'Queen of Hoyas' for its colossal, jewel-toned blossoms.
FUN FACT
The flowers of Hoya macgillivrayi are fleshy, glabrous and flattened bell-shaped, dark reddish-pink and sometimes with a white centre.
FOLIAGE AND GROWTH HABIT
Hoya macgillivrayi is an energetic, woody twining climber that demands a sturdy support structure such as a bamboo U-trellis, cedar plank, or steel hoop. Its leaves are thick, succulent, and broadly elliptical to ovate with heart-shaped bases and pointed tips, measuring 15 to 20 centimetres in length and 6 to 9 centimetres in width. The foliage is lustrous deep forest green with prominent pale venation that creates a refined, sculptural appearance. Under high indirect light with gentle morning sun, new leaf flushes can exhibit warm bronze-red undertones before maturing into thick, leathery shields.
FLOWER DETAILS
The inflorescence of Hoya macgillivrayi is widely considered one of the grandest floral spectacles in the plant kingdom. It bears loose, pendulous umbels composed of 6 to 12 gigantic flowers, each individual bloom measuring an astonishing 6 to 8 centimetres in diameter. The waxy corolla lobes are pointed and cupped, displaying an intense, glowing deep burgundy-red to ruby-crimson color, highlighted by an immaculate white-and-maroon star-shaped corona. The flowers open at dusk and release an intoxicating, powerful perfume reminiscent of spiced gardenia and cloves. Never remove spent flowering spurs, as they bloom repeatedly year after year.
CARE INSTRUCTIONS
🌞 Light: Prefers bright indirect light for 7 to 9 hours daily, with 1 to 2 hours of gentle morning sun to stimulate blooming. Shield strictly from intense midday summer rays, which can scorch the glossy leaf surfaces.
💧 Water: Follow a strict soak-and-dry watering routine: drench thoroughly when the top two-thirds of the chunky potting medium has dried out. Ensure flawless drainage, as soggy roots rapidly lead to root rot.
🌡️ Humidity: Thrives in elevated atmospheric humidity between 60% and 80%, reflective of tropical coastal Queensland. It benefits greatly from pebble trays or indoor humidifiers during dry Canadian heating seasons.
🪴 Soil: Demands an open, chunky, and well-aerated epiphytic substrate consisting of coarse fir bark, perlite, pumice, horticultural charcoal, and coco husk chips to ensure rapid drainage and generous oxygen exchange.
🏺 Potting: Plant in a substantial, heavy container with drainage holes to counterbalance its tall climbing canopy. Keep the plant slightly root-bound to trigger prolific flowering; repot only every 2 to 3 years in spring.
🌱 Growth rate: Fast grower during warm spring and summer months. Stems can elongate by 1 to 2 metres in a single season once trained securely onto a supportive trellis.
👩‍🌾 Fertilizing: Feed every 2 to 3 weeks during active growth with a balanced liquid houseplant fertilizer diluted to half strength, alternating with a bloom booster in early summer. Withhold fertilizer throughout late autumn and winter.
WHERE TO PUT IT
Hoya macgillivrayi deserves a prominent position in a bright living room, sunroom, or studio with ample vertical ceiling height. Position it adjacent to an east-facing window or 1 to 1.5 metres back from a large south-facing window with sheer curtains. Keep the plant in temperatures between 20°C and 28°C, and ensure it is safely protected from freezing Canadian winter window drafts and drying direct heat from radiators.
