Plant profile

Placement

Midground

It is an epiphytic plant that should be attached to hardscape materials like rocks or driftwood. It can be placed in the midground or background depending on the size of the specimen. Never bury its rhizome in the substrate, as this will quickly lead to rotting.

Botanical form

Rhizome

It features a creeping, woody rhizome from which broad, slightly lobed green leaves emerge. The fronds are somewhat translucent and less finely divided than its African counterpart, Bolbitis heudelotii. It has a robust, primeval appearance that adds an ancient feel to the aquascape.

Growth

Slow

When kept fully submerged, its growth rate is extremely slow and it may take months to produce a few new leaves. It grows significantly faster when cultivated emersed in high humidity, such as in a terrarium or paludarium. Under ideal aquatic conditions with CO2, growth only slightly improves.

Substrate

None

Bolbitis heteroclita is a true epiphyte that does not require any soil or conventional substrate to grow. Its creeping rhizome uses specialized roots to firmly anchor itself onto hardscape materials such as porous rocks, lava stones, or driftwood. Burying the rhizome in sand or soil will lead to rot, so it absorbs all necessary nutrients directly from the water column through its fronds and exposed root system.

Column fertilization

Recommended

Requires only very lean liquid fertilization to survive. A basic all-in-one fertilizer dosed sparingly is usually more than enough to maintain its green coloration. Heavy dosing of macronutrients is strongly discouraged unless the tank is heavily planted with fast growers.

Root fertilization

None

As a true epiphyte, it does not draw nutrients from the substrate and therefore does not need root tabs or aquasoil. It absorbs everything it needs directly from the water via its leaves and exposed roots. Tying it to a porous rock can help the roots anchor over time.

Trimming

Occasional

Maintenance is minimal and consists mainly of removing older, damaged, or algae-covered leaves. Always cut the leaf stem as close to the rhizome as possible using sharp scissors. Trimming away unhealthy foliage redirects the plant's energy into producing fresh, clean fronds.

Propagation

Rhizome division

Propagation is straightforward and is achieved by dividing the main rhizome. Ensure that each cut section retains at least a few healthy leaves and a viable portion of roots. Reattach the newly cut sections to a piece of hardscape using fishing line or plant glue.

Sensitivity

Moderate

The most critical sensitivity is the rhizome's intolerance to being buried in soil or sand. It is also sensitive to poor water circulation, which can allow detritus to settle on its broad leaves and invite algae. It often struggles to adapt permanently to submerged life, sometimes slowly declining over time.

Layout role

Midground, Background, Epiphyte

It is best used as an accent plant attached to wood in low-light or low-tech aquariums. Its dark green, broad leaves provide excellent contrast against fine-leaved stem plants and lighter green mosses. It also excels as a transitional plant breaking the water surface in shallow paludariums.
