Hoya vangviengiensis Ø12

Hoya vangviengiensis is a rare Hoya species from the Apocynaceae family, native to the limestone forests of the Vang Vieng region in Laos. It stands out for its thick, fleshy leaves with a robust waxy texture and an exotic appearance that immediately draws attention. Its flowers, grouped in fragrant umbels ranging from creamy yellow to pink, release a sweet, intense fragrance that intensifies in the evening. A moderately growing epiphyte, ideal for hanging baskets and rare species collections. Care instructions Hoya vangviengiensis grows as an epiphytic vine, producing long, flexible trailing stems that cling to any available support or cascade gracefully from hanging baskets. The growth rate is moderate - under optimal indoor conditions, expect 20-50 cm of new stem growth per year and 3-6 new leaf pairs per stem. Young stems are green and flexible, becoming semi-woody at maturity. Propagation is most efficiently achieved through stem cuttings with 2-3 nodes. Cut below a node with a sterilised blade, allow the cut end to dry for 24-48 hours, then place in moist perlite or filtered water. According to the RHS, rooting takes 4-8 weeks at 22-26°C, with an 85-90% success rate. Air layering is an excellent alternative for thicker stems. Care requirements are as follows: Light: Bright indirect (10,000-20,000 lux). East/west windows ideal. Avoid direct summer sun between 11-15. Minimum 8,000 lux for flowering. Temperature: 18-30°C, optimum 22-27°C. Minimum tolerable: 12°C briefly. A cooling period (15-18°C in winter) stimulates flowering. Watering: 'Soak and dry' method - saturate the substrate, wait for the top 4-5 cm to dry completely. Summer: every 7-12 days, winter: 14-25 days. Excess causes root rot. Humidity: 50-70% ideal, minimum 40% acceptable. A humidifier is preferred over direct leaf misting. Substrate: 40% pine bark (1-2 cm), 25% perlite, 20% coir, 10% horticultural charcoal, 5% dolomite (reflecting the limestone habitat). pH: 6.0-7.0. Fertilising: Balanced liquid fertiliser (NPK 20-20-20) diluted to half strength, every 2-4 weeks during the growing season (March-September). Stop fertilising in winter. Propagation: Stem cuttings with 2-3 nodes, in moist perlite or water. Air layering for mature stems. Optimal period: spring. Specifications Pot diameter: 12 cm Total height (incl. pot): 15 cm Flowering stage: No flowers
