Hoya cummingiana

Hoya cummingiana is a compact, upright-growing species with short internodes and small, firm green leaves held neatly along the stems. The flowers are yellow with a contrasting red centre, forming small umbels with a noticeable sweet scent. The species is native to the Philippines, typically found in warm, bright positions where it grows over shrubs and low vegetation.

The plant develops a tidy clumping form rather than a long trailing habit, making it suitable for smaller spaces or structured displays. It prefers warm temperatures, steady light and a lightly drying cycle. Growth can slow in cooler months, and the species may stall if temperatures fluctuate sharply.

Key Characteristics

• Growth habit: Compact, upright stems forming a bushy plant with short internodes
• Leaf features: Small, smooth, firm green leaves arranged closely along the stems
• Flowers: Yellow star-shaped blooms with red centres, produced in small umbels
• Fragrance: Sweet scent during active flowering
• Pot size supplied: 100 mm or 80 mm depending on batch; plant size remains consistent
• Growth speed: Moderate in warm, bright conditions
• Skill level: Intermediate - may stall or drop leaves if exposed to cold or fluctuating temperatures

Growing Conditions

• Light: Bright, indirect light; soft morning sun is suitable and encourages compact growth.
• Water: Allow most of the potting mix to dry before watering; avoid prolonged wet periods.
• Temperature: Best grown between 18-30 °C; sensitive to cold drafts and sudden temperature changes.
• Humidity: Standard indoor humidity is workable, though slightly higher humidity supports steady growth.
• Potting mix: Chunky, airy, free-draining mix with bark and coarse perlite to protect the roots from saturation.
• Fertiliser: Light feeding during the warmer months supports growth and flowering.
