Propagating Anubias barteri 'Variegata'

How to propagate the cream-variegated Anubias barteri 'Variegata' by rhizome division, keeping the rhizome exposed and giving good light to feed the slow variegated leaves.

Overview

'Variegata' is a cultivar of Anubias barteri, a West African Araceae species first described in 1860 from south-eastern Nigeria, Cameroon and Bioko. It carries cream-yellow variegation on green leaves. Because the pale tissue holds less chlorophyll, this cultivar grows even more slowly than the plain species and benefits from good light. Like all Anubias barteri it is an epiphyte whose rhizome stays above the substrate, tethered to rocks and wood.

Propagation Method (Rhizome Division)

Anubias barteri can be propagated by dividing the rhizome or by separating side shoots. The rhizome is the thick horizontal stem between the leaves and the roots, and new leaves emerge from it. To multiply 'Variegata', cut this stem into sections, each retaining enough variegated leaves and roots to survive on its own.

Step-by-Step

Remove the parent plant and rinse the rhizome to reveal the leaf and root spacing.
Pick divisions that keep at least three to four leaves each, favouring pieces with healthy green and variegated tissue.
Cut the rhizome cleanly with sharp, sterilised scissors so each section has its own leaves and roots.
Attach each division to driftwood or rock with a small line of super glue gel, pressing the roots for about 30 seconds, or tie it with thread until it anchors.
Place the divisions back with the rhizome fully exposed above the substrate.

Conditions for Healthy Growth

Keep 'Variegata' at 22-28 C (72-82 F). Anubias barteri tolerates a range of lighting, and in stronger light the leaves grow more quickly and stay compact; this variegated form in particular benefits from good light to support its pale leaf areas. No CO2 is required, and it grows well partially or fully submersed.

Maintenance

Once attached, the cultivar needs little care. Its leathery leaves last a long time, so trimming is seldom needed. Remove any rotting or heavily variegated leaves that fail to thrive, and leave fresh rhizome growth undisturbed while it grips the hardscape.

Common Challenges

Rhizome rot from burying the rhizome, the leading cause of loss.
Very slow recovery, slower than the green species, because variegated tissue produces less energy.
Weak or melting cream sections if light is too low for the cultivar.
Loose attachment if glue or thread is removed before roots grip the hardscape.
