Hoya serpens is a small trailing vine found in the Himalayas and surrounding areas.

The leaves are dark green, hairy, and have grey spots intermittently dispersed.

The flowers produced are extremely fuzzy with a light green corolla and a white corona with a bit of pink towards the center of the flower, with finally a yellow center.

The flowers last about a week, and unlike other Hoyas, produce very little nectar.

It was first discovered and published by Joseph Dalton Hooker in 1883.
