Origin
The Hoya callistophylla 'Sabah' is a unique climbing plant originating from the tropical rainforests of Borneo, specifically from the Sabah district. Its exact origin remains somewhat mysterious, as it's a relatively recent discovery within the botanical world.

Characteristics
The Hoya callistophylla 'Sabah' stands out due to its elegant appearance. The plant has long, hanging stems with glossy, smooth leaves that grow in an alternate pattern. The leaves have a striking colour gradient from light green to dark green, depending on the intensity of the light. Upon flowering, this Hoya produces unique clusters of waxy flowers, typically in the pink to lilac spectrum.

Care
Taking care of the Hoya callistophylla 'Sabah' requires some attention. The plant needs a lot of light, but not direct sunlight. In addition, the Hoya callistophylla 'Sabah' likes moderate amounts of water, but it is essential to ensure that the soil completely dries out between watering in order to prevent root rot.
