Hoya campanulata is a rare and elegant epiphytic Hoya native to western Malesia, including Borneo, Java, Malaya, and Sumatra, where it grows in wet tropical forests. It develops slender climbing stems with attractive, fleshy green leaves and produces distinctive bell-shaped, waxy flowers, which give the species its name. The flowers are typically produced in clusters and have an unusual campanulate form compared with the more familiar star-shaped flowers of many Hoyas. Its graceful vining habit, unusual floral structure, and rarity in cultivation make Hoya campanulata an appealing species for collectors of unusual Hoyas.
Care Tips:
Provide bright, filtered light with gentle morning or late-afternoon sun.
Use a chunky, airy, fast-draining substrate such as orchid bark, perlite, and coco-based materials.
Water thoroughly when the medium has dried substantially, allowing a wet-dry cycle while avoiding prolonged waterlogging.
Maintain 60–80% humidity with good air circulation.
Keep temperatures warm to intermediate, with slightly cooler nights beneficial for growth.
Provide a trellis or climbing support for its vining stems.
Fertilize lightly with a balanced fertilizer at ¼–½ strength during active growth.
Do not remove old flower peduncles, as Hoyas can rebloom from established spurs.
