Plantaginaceae

Lemon Bacopa

Bacopa caroliniana

A sturdy stem plant with thick leaves that smell faintly of lemon when crushed. It grows slowly and needs little attention, which makes it one of the calmest plants for a first tank.

Care and keeping

Appearance

Upright stems 10–60 cm tall with paired oval leaves, thick and slightly succulent. In strong light the tips take on a copper or rosy tint; otherwise the plant is a plain fresh green.

Keeping

Undemanding: dim light and hard water are fine, carbon dioxide is not needed. It grows slowly, so unlike most stem plants it does not need constant pruning. In an open tank it grows out of the water and flowers there.

Placement

The back and the middle of the tank, in small groups. It branches from the base, so a few stems soon close into a bush.

Propagation

Cut a side shoot and plant it in the substrate. Roots follow within a week or two — slower than with fast stem plants, but just as reliable.

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.
