Propagating Lagenandra meeboldii 'Red'

How to propagate the rhizomatous Lagenandra meeboldii 'Red' by dividing its rhizome and rooting offshoots, with care notes on its Anubias-like rhizome and crypt-style melting.

Overview

Lagenandra meeboldii 'Red' is an Araceae plant that grows from a rhizome, much like an Anubias, even though its broad leaves resemble those of a Cryptocoryne. It is commercially grown emersed and, when settled, can become a large specimen, growing to roughly 18 inches over time. Like crypts, it can melt after being moved and then regrow from the rhizome.

Because it is a rhizome plant rather than a stem, propagation is by rhizome division and offshoots, not by topping cuttings.

Propagation Method

The plant spreads as small pieces of rhizome occasionally break free and form new plants. You can cut or separate rhizome sections; even a piece with no leaves but a couple of small buds will sprout. Tissue-cultured stock typically yields several divisions, making it good value for propagation.

Step-by-Step

Identify a section of rhizome carrying at least one or two growth buds.
Cut or break it cleanly from the parent, the way you would divide an Anubias rhizome.
Float a leafless rhizome piece with buds, or place a leafed division at the substrate surface.
Anchor the roots in the substrate but keep the rhizome itself on top, never buried.
Within a week or two the division starts throwing up new leaves; pot it on once established.

Conditions for Healthy Growth

This is an adaptable, intermediate plant. It does fine with or without CO2 and, when grown submersed, often does better when slightly shaded rather than under intense light. Treat it as a root feeder in nutrient-rich substrate, with the rhizome resting at the surface like an Anubias.

Maintenance

Maintenance is minimal for this slow grower. Remove old or melted leaves, keep the rhizome firmly anchored at the surface, and be patient if the plant melts after a move; it usually regrows from the rhizome. Note the latex sap typical of the genus when cutting.

Common Challenges

Rhizome disintegration when the rhizome is buried in substrate.
Crypt-like melting after transplanting, followed by slow regrowth.
Suffering and stalling when plants are crowded together.
Slow leaf production, so divisions take time to fill out.
