How to read these metrics
These metrics are standardised reference points. We compile them by reviewing and cross-checking multiple botanical and horticultural references, then refining them through real-world growing experience. Source links: Plant Care Resources.
Please use the values as guidance. Conditions vary by home, so the same plant can respond differently. For plant-specific context, read the full product description and browse our Plant Care Guides.
- Light: level + approximate lux at leaf level;
- Watering: “% dry” is the trigger before watering again; lower % stays more evenly moist.
- Potting mix: one-line profile (structure/drainage • moisture buffer • base • particle size).
- Temperature: “Ideal” comfort range; “Avoid below” marks higher stress risk.
- Humidity: target bands (Normal/Moist/Humid); consistency usually matters most.
- Growth habit: growth form (rosette, trailing, climbing) for placement and training.
- Support: needed/optional/none — whether stake, pole, or trellis improves structure and size.

Hoya imperialis ‘Red’ – Giant-Flowered Tropical Vine for Bright Indoors
Hoya imperialis ‘Red’ is a bold, large-flowered cultivar of Hoya imperialis Lindl., a species known for producing the largest blooms in the genus. Each flower can reach up to 10 cm across and displays velvety, deep red petals with a subtle evening scent. Combined with thick, glossy green leaves and a vigorous vining habit, this plant is a must-have for collectors seeking an exotic, easy-care tropical houseplant.
Quick Facts: Hoya imperialis ‘Red’
- Flower size: Up to 10 cm diameter
- Light: Bright, indirect sunlight
- Growth habit: Slow to moderate vining climber
- Humidity: 60% or higher preferred
- Safe for pets: Non-toxic but not for ingestion
Key Features of Hoya imperialis ‘Red’
- Massive Blooms: Clusters of red, star-shaped flowers with a velvety texture and evening fragrance.
- Foliage: Large, thick green leaves with a waxy surface, approx. 10 cm long.
- Growth Form: A climbing tropical vine that can be trained on a trellis or allowed to trail in a hanging basket.
Care Guide for Hoya imperialis ‘Red’
- Light: Bright, indirect light promotes growth and flowering. Avoid harsh direct sun to prevent leaf scorching.
- Watering: Let the top 2 – 3 cm of soil dry before watering. Reduce watering frequency in lower light or cooler conditions.
- Humidity: Prefers 60% or higher. Use a humidifier or cluster with other plants to increase ambient humidity.
- Soil: Use a chunky, well-draining mix: orchid bark, perlite, and coco coir or peat-free potting soil.
- Temperature: Ideal range is 18 – 26 °C. Avoid cold drafts and temperature extremes.
- Feeding: Apply a balanced liquid fertilizer monthly throughout the year. No need to adjust seasonally.
Encouraging Blooms on Hoya imperialis ‘Red’
- Keep slightly root-bound – this often encourages flowering in mature plants.
- Maintain bright, indirect light consistently throughout the year.
- Reduce watering slightly in cooler months to simulate dry season triggers.
Common Issues and Solutions
- Yellowing Leaves: Often caused by overwatering. Check drainage and let the soil dry out more between waterings.
- Drooping or wrinkled leaves: Can signal underwatering or low humidity. Adjust watering and environment accordingly.
- Pests: Watch for spider mites, mealybugs, and aphids. Treat early with neem oil, insecticidal soap, or beneficial insects.
- Lack of blooms: Ensure sufficient light, avoid oversized pots, and maintain consistent feeding.
Growth and Display Tips
- Training: Provide a trellis or hoop to encourage vertical growth. Prune lightly to maintain shape and promote bushiness.
- Repotting: Every 2 – 3 years or when rootbound. Use a pot with good drainage.
- Cleaning: Wipe leaves gently with a damp cloth to remove dust and improve photosynthesis.
Natural Habitat
Hoya imperialis is native to lowland tropical forests of Borneo, the Philippines, and parts of Malaysia, where it grows as an epiphyte in warm, humid, shaded environments. Mimicking these conditions – filtered light, high humidity, and good airflow – will help the plant thrive indoors.
Etymology
The genus Hoya was named in honor of Thomas Hoy (c. 1750 – 1822), an English botanist and horticulturist. The species name imperialis refers to the regal, crown-like appearance of its massive blooms. The cultivar name ‘Red’ highlights the flower’s deep crimson color, which distinguishes it from other forms such as pink or white.
Taxonomic citation: Hoya imperialis Lindl., published in Bot. Reg. Sub T. 68 (1846).
