Onagraceae

Marsh Ludwigia

Ludwigia palustris

A red plant that manages without carbon dioxide and asks only for decent light. It branches readily, so a few stems soon become a bush.

Care and keeping

Appearance

Stems from 10 to 50 cm with small oval leaves in pairs — green above and red-purple underneath, and wholly red in strong light. The plant sends out side shoots on its own and grows dense.

Keeping

Easy: it grows in soft and hard water, tolerates dim light and does without carbon dioxide, though the red comes only with light. Trimming makes it branch more, which is the simplest way to a full group.

Placement

The middle and back of the tank as a colour accent; the shorter forms suit a nano tank. Plant several stems together — a red spot works, a single red stem does not.

Propagation

Cut a shoot and plant it; roots appear in a few days. Cuttings taken from side shoots root just as readily.

Fish and this plant

Matching water does not mean the fish will leave the plant alone.

Cultivars

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