Java fern also will root onto wood - forgive me if you have it listed. I don't know the scientific name.

 

Thanks aclaar877,

And yes, Java Fern = Microsorum pteropus.

 

Does the lack of response mean that I've made a complete list? I was sure that I had missed 1 or 2 available aquatic epiphytes / lithophytes.

As for, Hemianthus callitrichoides, is there no one with knowledge about their ability to root on objects?

 

I tried them and they never root. But tying them with fishing line that does not rot can keep them intact with the wood giving it an appearance that it looks attached. Covering it with moss can be a good way to hide the fishing line. Add lots of liquid ferts to sustain them. You can also try dwarf sag in this method. My saggitaria platyphylla attached to a DW covered with moss looks awesome.

 

Those are all the ones that I'm aware of...

 

HC will root on to something like lava rock, but not on something inert/no CEC.

 

Thanks you three!

I'm glad to have compiled a complete list of available aquatic epiphytes and lithophytes! In time I'm sure there will be more to add.

Great news about the Hemianthus callitrichoides rooting on to lava rock. That's exciting!
What is "CEC"?

And for the sake of completeness, here is the list:

Anubias sp.
Bolbitis heudelotii
Bucephalandra sp.
Hemianthus callitrichoides
Hygrophila pinnatifida
Microsorum pteropus
A variety of Mosses (Taxiphyllum, Fissidens, etc.)

 

CDC = cation exchange capacity

Any plant can root into lava rock since lava rock contains a lot of metals and can adsorb a lot of metals that the plants can use, hence the reason its roots will grow into it. However, HC can be used for good effect on both small pieces and large pieces of lava rock.

 

Thanks for the explanation Solcieo lawrencia.

I thought of another . . . Utricularia graminifolia! I'm on a Carnivorous Plant forum and people grow UG on rocks, wood and a few other media. So adding to the list:

Anubias sp.
Bolbitis heudelotii
Bucephalandra sp.
Hemianthus callitrichoides
Hygrophila pinnatifida
Microsorum pteropus
A variety of Mosses (Taxiphyllum, Fissidens, etc.)
Utricularia graminifolia

 

Boom! Here's 2 more for ya!

Schismatoglottis roseospatha
(And I've read that there are possibly other Schismatoglottis that may grow fully aquatic.)

Aridarum (Could not find what exact species is fully aquatic).

 

I've read that subwassertang will root on to objects. However, it seems that this happens only for some and not for others.

However, many might confuse subwassertang with pellia and pellia will not attach to objects.

What is your experience with subwassertang?

 

I've read offhand reports of Marsilea minuta rooting to wood. I had some extra and am giving it a try in my 150G.

 

Pogostemon helferi (aka Downoi) will also root to rocks and prob wood as well. I think good flow might be a key for them - they're from fast water environments.

 

True mosses (note: riccia and marimo are not mosses), and any member of the fern or anubias family. There are quite a few options for all 3.

 

Thanks for the contribution you three!

It is beautiful!

This is good, thanks Acro

 

Riccia definitely roots!

 

I had no idea that UG could root on volcanic rock, that's friggin awesome!

 

UG can root onto other objects besides lava rock. A guy on a carnivorous plant forum I'm on, has experimented with it and this is what he had to say:

I have grown this stuff in everything from rockwool, mud, gravel, clay pellets, moist driftwood, ADA aquasoil, sphagnum moss, other mosses, rocks, on top of other plants, on plastic (99% humidity tank, its growing on some worm feeders), on top of airline tubes, glass (its growing on the side of the glass in a 99% humidity tank, on the side nothing holding it there) and probably a few more things I've forgotten about. It has grown in every medium just fine under alot of different lighting levels. I have some growing under a single 14W compact flourscent, all the way up to some growing under 4 T5HO bulbs and lots of levels between.

I have my UG growing on an Exo-Terra Waterfall, some of it is completely under water, some of it is in the waterfall's current.

 

Bolbitis heteroclita.. Asian water fern.. much easier to root emersed but will root submersed in time.

How could I forget! There's another one, that I've known about (and I grow), but I didn't think of till now! Let me introduce: Red Mangrove!

Rhizophora mangle (Red Mangrove). It will root onto rocks. This may be considered more of a "Riparium" plant, but either way, it is a wonderful addition to an aquarium, riparium, or paludarium!

The Black Mangrove (Avicennia Germinans) has become available recently, does anyone know if it will root onto rocks?

 

Time for updates!

I've learned that some Cryptocoryne (aka Crypt) species will root onto rock.

A few months ago, someone told me that they had Cryptocoryne hudouri root onto dragon stone.

I also found the company Tropica selling Cryptocoryne petchii rooted onto lava rock. Check it out here:
http://www.aquaessentials.co.uk/blog/2014/03/cryptocoryne-petchii-grown-on-lava-rock.html

And the company AquaEssentials is selling Cryptocoryne on rock.
Cryptocoryne (Species?):

Here is more proof that Crypts can root onto rock (you might need to translate it, but photos speak a thousand words):

Have fun! Experiment! And if you have any plants to add . . . post up!

 

Monoselenium tenerum - I'm not sure if you have classified this among the mosses but it's not a moss, it's a liverwort. Grows easily on lava rock.

 

Thanks Daisy Mae!

Tropica has this to say about Monosolenium tenerum: "Rhizoids can anchor the plant to stones or tree roots, but this attachment is not particularly effective under water."

Only plants that root onto submerged objects are added to the list! Have you had Monosolenium tenerum root solidly under water? Let the forum know!

 

Got a bit of süßwassertang several months ago and just thrown it into a tank as I wasn't sure where to plant it. Was rescaping this tank last week and found that it all attached itself to substrate - regular Petco gravel.

 

Got a bit of süßwassertang . . . and found that it all attached itself to substrate - regular Petco gravel.

Nice! Glad to hear that a listed plant is working for you as advertised!
How well were the roots attached?

What about monte carlo?

It seems that Micrantherum umbrosum (aka monte carlo) will root onto rock. I recently heard from another member and they said "I've had it spread to and grow/root into lava rock". Another plant to add to the list!

. . . the Monoselenium . . . anchored well enough that I had to rub it off in order to salvage the rock.

Thanks for sharing your experience! Although this is the first report I've ever heard of it bonding to rock (and many members have tied it to items), I will add it to the list! Hopefully others will add their experience.

What about monte carlo?
