Aquarists in Thailand, close to the border with Burma, discovered this plant. It is called ‘Downoi’ (little star) in Thailand, and it is easy to see why (5-10 cm tall and wide). Pogostemon helferi is an unusual and distinctive aquatic plant with a compact habit, curly leaves and a strikingly beautiful green colour.
With good light conditions and a nutrient-rich substrate, Pogostemon helferi forms many side shoots that develop small roots, and the plant rapidly forms an impressive carpet of foreground vegetation.
