Hoya calycina

Hoya calycina is a vigorous tropical climbing Hoya native to New Guinea and the Bismarck Archipelago, where it grows primarily in wet tropical habitats. It develops long, twining stems with large, thick, leathery green leaves and can form an impressive mature vine. The species is especially appreciated for its large, waxy, star-shaped flowers, which are typically creamy white to pale yellow with a contrasting reddish to pink corona and are produced in rounded clusters. Its substantial foliage, vigorous growth, and attractive, relatively large flowers make H. calycina a desirable species for collectors and greenhouse cultivation.

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 upper portion of the medium begins to dry, avoiding prolonged waterlogging.
• Maintain 60–80% humidity with good air circulation.
• Keep temperatures warm to intermediate, protecting the plant from prolonged cold.
• Provide a trellis or climbing support for its vigorous vining growth.
• Fertilize lightly with a balanced fertilizer during active growth.
• Avoid removing mature flower peduncles, as established spurs can produce new flower clusters.
