Pogostemon helferi (dao-noi, meaning "little star") is a small aquatic mint-family plant from Southeast Asia, widely grown in aquariums. It thrives submerged in clean, well-lit tank water and is mostly harvested from the wild.
Pogostemon helferi, also known as dao-noi, is a species of Thai aquatic plant. It is a common ornamental plant in aquariums.
Pogostemon helferi is distributed across Myanmar and western Thailand. A 2005 survey conducted in Thailand found the species in north, north-east, east, and west Thailand. However, a 2007 survey found the species only in the Kanchanaburi province, found near Myanmar. A 2024 review found the species distribution extending to the Indian Himalayan Region.
