“Daonoi” is an odd plant growing in fast-flowing rivers in northwest Thailand on limestone. It was long only known to science, but some years ago, some aquarists from Thailand discovered it for the hobby. It is characterised by compact growth, curly leaves and a nice light green hue.

Also called “daonoi” or “downoi” (Thai for “litte star”), Pogostemon helferi has been known to science for over 120 years, however, it was only discovered for aquaristic purposes in 1996, by Nonn Panitvong and Arthit Prasartkul, who found it in the Thai province Kanchanaburi, on the border to Myanmar. Within only a short period, P. helferi has become a very popular aquarium plant for the fore- and middle ground.
