Pogostemon Helferi 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.

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.
