How to read these values
These care values are quick reference points for indoor growing. Use them as a guide, then adjust for pot size, substrate, temperature and how quickly the substrate dries.
For more detail, read the full product description or visit our Plant Care Guides.
- Light: level and approximate lux at leaf level.
- Watering: “% dry” shows how far the substrate should dry before watering again.
- Substrate: structure, drainage, moisture retention, base material and particle size.
- Temperature: “Ideal” shows the preferred range; “Avoid below” marks the cold-stress threshold.
- Humidity: target range; steady conditions usually matter more than exact numbers.
- Growth habit: how the plant grows, such as upright, climbing, trailing, clumping or rosette-forming.
- Support: whether a stake, pole or trellis is needed, optional or unnecessary.
- Growth speed: expected pace under suitable indoor conditions; use as a guide, not a promise.
- Max size indoors: realistic long-term indoor size under good conditions.
- Toxicity & safety: irritation, toxicity or physical hazards such as spines or bristles.
- Origin & habitat: native range, hybrid background or typical habitat where relevant.
- Outdoor growing: when a potted indoor plant can be placed outside and what outdoor protection it needs.
Hoya clemensiorum – Textured Foliage from the Rainforests of Borneo
Hoya clemensiorum (T. Green) is a rare and striking climbing epiphyte, native to the tropical rainforests of Sabah, Borneo. Known for its deeply veined, crocodile-textured leaves, this species has become a cult favorite among serious Hoya collectors. Slow-growing but visually stunning, it brings a bold jungle flair to bright indoor spaces.
Standout Traits of Hoya clemensiorum
- Remarkable Leaf Texture: Elongated, leathery leaves with raised, dark green venation resembling carved stonework – up to 40 cm long.
- Climbing Growth Style: Grows as a vining epiphyte, best trained on a moss pole or hanging basket for aerial root support.
- Rare Blooms: Clusters of small, waxy, star-shaped flowers with a musky citrus fragrance. Flowering indoors is rare and slow to initiate.
- Native Habitat: Endemic to lowland forests in Sabah (East Malaysia, Borneo), thriving in high humidity and dappled light.
- Taxonomic Notes: Described by Ted Green in 1991, formally named Hoya clemensiorum (T. Green)
Indoor Care Guide for Hoya clemensiorum
- Light Requirements: Prefers bright, indirect light. Avoid strong midday sun to prevent leaf scorch.
- Watering Routine: Let the top 2 – 3 cm of substrate dry out before watering. Always water deeply and allow excess to drain.
- Humidity Needs: Keep air humidity between 60 – 80%. Boost with a humidifier in drier seasons.
- Best Substrate: Use a chunky, well-aerated mix – orchid bark, perlite, and coco coir ensure healthy roots.
- Fertilization: Feed monthly with a balanced liquid fertilizer at half strength. No seasonal break needed.
Troubleshooting Tips for Hoya clemensiorum
- Yellowing Leaves: Usually a sign of overwatering. Check that the pot drains freely and allow more drying time.
- Root Issues: Rot can occur in compact or soggy soil. Switch to a looser mix and ensure aeration.
- Common Pests: May attract mealybugs or spider mites in low airflow. Treat early with neem oil or insecticidal soap.
