Pogostemon yatabeanus
Pogostemon yatabeanus is a vibrant stem plant native to Southeast Asia, prized for its distinctive narrow, lance-shaped leaves that display rich green coloration with reddish undersides under strong lighting. This plant exhibits a compact, bushy growth habit and is moderately fast-growing, making it an excellent choice for midground placement in planted aquariums.

Proserpinaca palustris
Mermaid Weed is a unique stem plant that changes leaf shape depending on whether it is emersed or submersed — submerged leaves are deeply serrated and comb-like, while emersed leaves are broader and simple. Under high light the deeply lobed leaves turn intense shades of orange and red, making it a striking colour accent in Dutch and Nature Aquarium layouts.

Pygmy Chain Sword
Echinodorus tenellus
Echinodorus Tenellus, the Pygmy Chain Sword, is a dwarf sword plant that forms a low, grass-like foreground carpet via prolific runners. Its narrow, strap-like leaves rarely exceed 10 cm, making it one of the few true sword plants suitable for foreground use. Under good lighting and CO2 it spreads rapidly; without CO2 growth is slower but still achievable.
Pygmy Chain Sword Red
Helanthium tenellum 'Red'
Red-tinted form of the Pygmy Chain Sword. Develops reddish-brown tones under higher light. Low-maintenance carpeting plant.
