✨ Hoya undulata 'Splash' – a rare botanical treasure with wavy silver-splashed leaves

General description

• Spectacular silver splash variegation: Rigid, lance-shaped leaves with distinctive undulate (wavy) margins, adorned with shimmery silver-white splashes that create an iridescent effect visible only in person.
• Color-changing foliage: Leaves range from olive green to deep burgundy depending on light levels, offering a dynamic display throughout the seasons.
• Rare and collectible: One of the most sought-after hoya varieties for serious collectors, native to the lowland heath forests of Borneo (Kalimantan), described botanically only in 2015.
• Magnificent white flowers: Large, star-shaped, porcelain-white flowers speckled with red on the outer petals – a reward for patient and skilled growers.

How to care for Hoya undulata 'Splash'

• Light: Bright indirect light is essential for growth. Interestingly, the silver splash variegation is more prominent when grown in partial shade rather than very bright light. Avoid direct afternoon sun which can scorch leaves.
• Watering: This is the most critical aspect – water ONLY when completely dry, no more than once weekly. Overwatering is the primary cause of failure with this species. Allow substrate to dry thoroughly between waterings.
• Soil: Use an extremely well-draining epiphyte mix – orchid bark, perlite, and chunky materials. Avoid moisture-retaining substrates. Net pots or terracotta pots are ideal.
• Temperature: Prefers warmth between 20–28°C. Benefits significantly from bottom heat (heat mat). Avoid cold drafts and temperature fluctuations.
• Humidity: Moderate to high humidity (50-70%) helps prevent leaf drop, though less critical than proper watering practices.
• Important note: This is considered one of the most challenging hoyas to cultivate. Best suited for experienced hoya collectors.
