Downoi
Pogostemon helferi
Family: Lamiaceae
Pogostemon helferi (Downoi or Little Star) is a distinctive, star-shaped rosette plant from Thailand with deeply ruffled, wavy-edged bright-green leaves radiating from a central crown. It grows low (5–8 cm) and is one of the few compact foreground rosette plants with real textural interest. It requires medium to high light and benefits from CO2 and soft, slightly acidic water. Popular in detailed Iwagumi and Nature Aquarium aquascapes.
