Hoya 'Chouke' – A Delicate Hybrid with a Botanical Backstory

Hoya 'Chouke' is a compact epiphytic hybrid born from an open pollination between Hoya carnosa R.Br. (1813) and Hoya serpens Hook.f. (1883). It was introduced in 1995 by Belgian grower Emilio Begine, who named it in honor of his wife. Sharing its origin with the better-known 'Mathilde', 'Chouke' offers a more vigorous trailing habit and larger, less speckled leaves. With its unique parentage and romantic naming story, it's a collector-worthy addition that brings charm and subtle fragrance to any indoor space.

Indoor Care Guide for Hoya 'Chouke'
 
Light: Bright, indirect light is ideal. Tolerates lower light but blooms best with stronger filtered light.
 
Watering: Let the top 2 – 3 cm of soil dry between waterings. Avoid soggy roots to prevent rot.
 
Humidity: Prefers 50 – 60%. Grouping with other plants or using a humidity tray is better than misting.
 
Temperature: Ideal range is 18 – 26 °C. Protect from drafts and cold below 12 °C.
 
Soil Mix: Use a well-draining substrate (orchid bark, perlite, coco coir) to replicate epiphytic conditions.
 
Feeding: Fertilize monthly with a balanced liquid fertilizer during active growth; avoid high nitrogen formulas.
 
Pruning: Trim only for shape. Never remove peduncles – flowers reappear from the same site.
Common Problems and How to Fix Them
 
Yellow Leaves: Often due to overwatering or compacted substrate. Improve aeration and reduce watering frequency.
 
Browning Tips: Usually from low humidity or salt buildup. Increase humidity and flush the potting mix monthly.
 
Pests: Watch for mealybugs, spider mites, and scale. Treat with neem oil or insecticidal soap.
 
Leaf Drop: Can occur after sudden changes in environment. Keep lighting, watering, and temperature stable.
Extra Growing Tips for Healthy Hoya 'Chouke'
 
Growth Speed: Moderate indoors. Flowers may appear within 1 – 2 years if conditions are steady.
 
Support Options: Hanging baskets work well, or use a mini hoop or trellis for structured growth.
 
Propagation: Root stem cuttings with at least one node in water or a moist, airy substrate.
 
Airflow: Good circulation helps prevent mildew and supports stronger foliage growth.
Safety and Handling
 
Toxicity: Not considered toxic to pets or humans but ingestion may cause mild digestive discomfort.
 
Latex Sap: Like many Hoyas, pruning releases a sticky sap that may irritate skin. Use gloves if sensitive.
