Phrymaceae

Dwarf Microcarpaea

Microcarpaea minima

Very fine needle-shaped leaves in pairs along thin stems. It can be cut low into a carpet or left to grow into a soft cloud of green at the back — rare, and not as delicate to keep as it looks.

Care and keeping

Appearance

Narrow leaves a few millimetres long in opposite pairs on slim stems. At a glance it is close to pearlweed and mayaca; the paired leaves are what tell it apart.

Keeping

Moderate demands with one clear requirement: strong light. In the shade the stems stretch and the group thins out. Carbon dioxide is not required, though it makes the growth denser. Trimming decides the shape — cut it often for a low carpet, leave it for a rounded bush.

Placement

The front of the tank as a fine carpet, or the middle and back as a soft hedge. Its size suits a nano tank.

Propagation

By cuttings: replant the trimmed tops.

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.
