Hoya fungii 'White'

🌿 Hoya fungii, commonly known as White Hoya fungii, is a climbing species within the Apocynaceae family. Native to the limestone cliffs of southern China and northern Vietnam, this plant thrives in warm, humid environments where it clings to rocks and trees. With its compact growth and manageable care needs, it's suited for intermediate growers who want something a bit different without overwhelming complexity. Here's a fun fact: Hoya fungii is named after the botanist Fung, who contributed significantly to the study of Asian Hoyas, and its waxy flowers can last for weeks once they appear.
FOLIAGE AND GROWTH HABIT
This Hoya has a climbing habit, often producing long vines that can be trained on a trellis or allowed to cascade from a hanging basket. The leaves are small to medium-sized, typically oval to lance-shaped, with a slightly pointed tip. They're thick and succulent-like, displaying a deep green colour with occasional lighter veining. The texture is smooth and waxy, giving them a polished, almost plastic-like appearance that reflects light beautifully.
FLOWER DETAILS
Hoya fungii produces clusters of star-shaped flowers that are creamy white to pale yellow, with a contrasting dark maroon or burgundy center. The blooms have a waxy texture and emit a light, sweet fragrance that's most noticeable in the evening. They're visually striking due to the colour contrast and the way they form tight, rounded umbels. This plant typically flowers during warmer months when it receives adequate light and has matured sufficiently. To encourage blooming, maintain consistent watering during the growing season, provide bright indirect light, and avoid moving the plant once flower stalks appear, as disturbance can cause bud drop.
CARE INSTRUCTIONS
🌞 Light: Bright indirect light works best, though it tolerates some morning sun. Aim for 4-6 hours of filtered light daily to support healthy growth and flowering.
💧 Water: Water thoroughly when the top half of the soil dries out, typically every 7-10 days in summer and every 2-3 weeks in winter. Bottom watering or slow soaking allows the roots to absorb moisture evenly without waterlogging.
🌡️ Humidity: Prefers 50-70% humidity but adapts to average home levels around 40-50%.
🪴 Soil: Use a chunky, well-draining mix with orchid bark, perlite, and a bit of peat or coco coir to prevent root rot.
🏺 Potting: A small to medium plastic or terracotta pot with drainage holes is ideal. Hoyas like being slightly rootbound, so repot only every 2-3 years when roots visibly crowd the container.
🌱 Growth rate: Moderate. Expect 15-30 cm of new growth in the first year under good conditions, with vines potentially reaching 1-2 meters at maturity.
👩‍🌾 Fertilizing: Feed monthly during spring and summer with a balanced liquid fertilizer diluted to half strength. Reduce or stop fertilizing in fall and winter.
🐾 Pet friendly: No. Hoya fungii is considered mildly toxic to cats and dogs. Ingestion may cause drooling, vomiting, or gastrointestinal discomfort due to the plant's sap.
WHERE TO PUT IT
Hoya fungii does well in living rooms, bedrooms, or home offices where it can receive bright, filtered light near an east or west-facing window. It's also suitable for bathrooms with good natural light, as the added humidity benefits the plant. Avoid placing it in dark corners, drafty hallways, or directly under air conditioning vents, as low light and temperature fluctuations can stunt growth and prevent flowering.
