Appearance

Compact, close-set leaves along a stem 10–20 cm tall, so the plant looks dense from top to bottom. Colour runs from plain green to red-brown and purple under good conditions. Several plants in the trade belong here under different names, and their underwater forms look quite unlike one another.

Keeping

Moderate demands: medium light, carbon dioxide helpful rather than essential, ordinary feeding. It branches willingly, and pinching the stems is what keeps the bush tight. Growth is average for the genus — quick enough to fill a space, slow enough not to take over.

Placement

The middle or back of the tank, in a group; its even, compact shape also suits the ordered rows of a Dutch-style layout.

Propagation

By cuttings: cut the top and plant it; the old stem branches below the cut.

Water conditions match

The water suits 1016 of 1249 species in the catalogue — these are the ones people look up most often.

The same plant with a different look: light, water and care are shared with the species.
