Hoya calycina

Hoya calycina is a distinctive species noted for its large, thick leaves and generous clusters of fragrant white flowers. The foliage is broad, smooth and firmly textured, sitting along strong vining stems that climb readily when supported. Flowers are white with pale to buttery centres, forming substantial rounded clusters with a sweet, noticeable scent.

The species grows best in bright filtered light with warm, stable temperatures and a lightly drying cycle. Its thicker leaves respond well to steady conditions, and the plant benefits from regular feeding during the warmer months to support flowering. Growth is reliable when humidity and temperature remain consistent.
