Acanthaceae

Temple Plant

Hygrophila corymbosa

A large stem plant with broad bright-green leaves, sold in many forms from narrow-leaved to red. It grows fast, so the pruning shears come out often — that is the price of a full back wall in a month.

Care and keeping

Appearance

Sturdy upright stems 20–30 cm tall with long broad leaves in pairs. Forms differ a great deal: some have narrow leaves, some reddish ones, and above water the leaves are firmer and darker.

Keeping

Moderate light suffices and carbon dioxide is not required, but it grows quickly and demands attention: without regular cutting the tops reach the surface, shade everything below and the lower leaves fall. Poor light produces bare stems with a tuft on top.

Placement

The back wall, in a group. In an open tank it readily grows out of the water and goes on above the surface.

Propagation

Cut a stem into pieces about ten centimetres long, strip the lowest leaves and plant them; roots form quickly. New shoots break from the cut stem and make the group bushier.

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.
