The Agapetes serpens belongs to Ericaceae (the Azalea family). It is an evergreen shrub that is distributed from eastern Nepal to Arnachar Pradesi in India. It grows at an altitude of 1500 to 2700 m at the foot of the Himalayas, and it grows in the woods and occasionally grows in the ground. The height is about 50 cm, but it will be longer if it climbs a wall. In early summer, bright red tubular flowers hang down from the axils. The flowers have a deep red chevron, often with a yellow tip.
