Hoya Endauensis, is a rare and striking hoya named after the Ulu Endau River in Johor, Malaysia, where it was first collected in 1985. Its light to olive green obovate leaves with undulating edges create a textured backdrop for its dazzling blooms. The small, fuzzy flowers feature a bright orange corolla, a red corona, and a golden-yellow center, releasing a sweet fragrance when in bloom. Though known for being more challenging than other hoyas, its breathtaking orange blossoms make the effort well worth it for dedicated collectors.
