Hoya lockii Yellow

Hoya lockii Yellow is a rare cultivated form of Hoya lockii from Vietnam, distinguished by its yellow flowers. The standard Hoya lockii was formally described from Vietnam in 2012 and is known for its upright growth, prominent leaf venation, and white, opalescent flowers with a strong chocolate-like fragrance at night.

Care Tips:

• Light: Provide bright, filtered light or several hours of gentle morning sunlight. Hoya lockii naturally grows high in trees, so it can tolerate relatively bright conditions, but harsh midday sun should be avoided.
• Watering: Allow the growing medium to partially dry before watering thoroughly. Avoid keeping the roots constantly wet.
• Growing Medium: Use a chunky, airy, fast-draining mix such as orchid bark, perlite, and organic material.
• Humidity: Moderate to high humidity around 60–80% is beneficial, with good airflow.
• Temperature: Keep warm to moderately warm, ideally around 18–30°C (65–86°F). Avoid prolonged exposure to cold temperatures.
• Airflow: Good air circulation is especially important when growing this Hoya in high humidity.
• Fertilizing: Feed lightly with a diluted balanced fertilizer during active growth.
• Support: Unlike many trailing Hoyas, Hoya lockii has a more upright growth habit, so a simple stake or support can help keep the plant upright.
• Flowering: Avoid moving the plant or making major changes to watering and light once buds develop. The Yellow form is notable for its unusually long-lasting flowers.
• Fragrance: The flowers are reported to release a strong chocolate-like fragrance at night, making evening observation especially rewarding.
