What’s Worth Knowing About Hoya carnosa 'Krimson Queen Splash'
 
Hoya carnosa naturally occurs from India through Southeast Asia, growing as an epiphytic climber in warm, humid tropical forests. There, it experiences steady temperatures of roughly 18–28 °C with moderate seasonal rainfall, and benefits from bright dappled light under the forest canopy. Indoors, Krimson Queen Splash tends to stay around 1–2 m long if supported, with its semi-woody growth habit lending a flexible structure for climbing or trailing. Growth speed is moderate to quick in good conditions. Like most Hoyas, it is considered mildly toxic to pets and humans if ingested (sap irritation is also possible on contact). This cultivar’s lifecycle is perennial, with potential flowering for many years if kept healthy.
