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 'Joy' – A Captivating Hybrid with Dynamic Foliage
Hoya 'Joy' is a remarkable hybrid between Hoya sp. Laos and Hoya vitellina, developed by hybridizer Michael Miyashiro. This plant is celebrated for its large, glossy leaves adorned with prominent silver spots that can develop a striking red hue under bright light. Its clusters of pink to peach flowers emit a subtle, pleasant fragrance, making it a delightful addition to any plant collection.
Key Features
- Foliage: Broad, dark green leaves with prominent silver splashes; foliage may turn reddish under intense light.
- Flowers: Umbels of up to 30 reflexed flowers, featuring pink to peach corollas and light pink coronas; emits a fresh, mild scent.
- Growth Habit: Semi-vining with a slow growth rate; suitable for hanging baskets or trellises.
Care Guidelines
Light
- Thrives in bright, indirect light; can develop a reddish hue under such conditions.
- Insufficient light may lead to reduced variegation and slower growth.
Watering
- Allow the top 2 – 3 cm of soil to dry out between waterings.
- Reduce watering frequency during cooler months or lower light conditions.
Humidity
- Prefers moderate to high humidity levels but can adapt to average indoor humidity.
- In drier environments, consider using a humidifier.
Soil
- Requires a well-draining, airy mix; a combination of orchid bark, perlite, and potting soil is ideal.
Temperature
- Optimal temperature range: 18 – 24°C (64 – 75°F).
- Protect from temperatures below 15°C (59°F).
Fertilization
- Feed monthly during the growing season with a balanced liquid fertilizer diluted to half strength.
Pruning
- Minimal pruning required; trim leggy growth to encourage bushiness.
- Important: Do not remove peduncles (flower stalks), as new blooms emerge from these structures.
Support
- Provide a trellis or stake to support and guide vining growth.
Common Issues and Solutions
Yellowing Leaves
- Cause: Overwatering or poor drainage.
- Solution: Allow soil to dry between waterings and ensure the pot has adequate drainage.
Browning Leaves
- Cause: Excessive direct sunlight.
- Solution: Move the plant to a location with filtered light.
Pests
- Common Culprits: Spider mites, mealybugs, and fungus gnats.
- Solution: Treat infestations with insecticidal soap or neem oil; maintain proper air circulation.
Root Rot
- Cause: Prolonged overwatering leading to soggy soil.
- Solution: Repot the plant using fresh, well-draining soil and reduce watering frequency.
Additional Tips for Success
- Placement: Position near an east or west-facing window to provide ample indirect light.
- Repotting: Only repot when the plant becomes root-bound; Hoyas prefer slightly snug pots.
- Propagation: Can be propagated through stem cuttings, but it is slow to root and commence growth.
Etymology
