Re: Aquatic aroids

Dear All,

At  least one species, (and probably several other species) of Spathiphyllum, S. cannifolium (which is an aroid of my EARLY childhood on Trinidad, W.I.) grows with its roots, rhizome and sometimes the lower part of its petioles in running water on the sides of streams.  It, and other Spaths, will NOT survive long with leaves completely underwater.

Almost all the Spathiphyllum I grow are in the house as house plants.  There are three in the atrium but they don't appear to like all the water from the overhead misting system and almost never produce an inflorescence.  It is my opinion that is because all of these are hybrids (not species) and have been bred to survive on minimal water and in low light.  But I thought for certain I had read in some of Dr. Croat's material that Spathiphyllum do in fact grow in water.  I asked him if the genus was a marginal.  This is the note he just sent, "Steve:  If you mean by “marginal” that they are along the margins of streams, yes, but they also occur out in the depths of the understory, sometimes in full sun too, especially along wet banks.  The genus is a hog for water and probably would not do well in really dry sites.

Hello,

I don't recommend Spathiphyllum - it is not an aquatic plant although it is 
often sold in aquaristic shops. It usually dies after a few months spent in 
water.
You can also sometimes find Syngonium, Epipremnum, Aglaonema, Alocasia, 
Dieffenbachia, Homalomena and Caladium sold as "water plants" -
they are also not aquatic and they rot living underwater.
Cyrtosperma is too large for your aquarium, it can grow half submerged - the 
roots in the water and the leaves above,
then you should have installed additional lighting above the leaves.
In your smaller aquarium I suggest you to create a paludarium - plants 
growing in wet peat with a fertilizer.
This way you can cultivate many aroids, all these which require high 
humidity
(Alocasia, Colocasia, many Anthuriums, Zantedeschia, Spathiphyllum)
but not these which fall into dormancy (like Amorphophallus or Arisaema).
A paludarium is also a better place for many Anubias species than an 
aquarium.
You can have in any aquarium Lemna, Spirodela and Pistia but many fishes 
like to eat them.
If it is not too hot you can try Calla palustris, Orontium aquaticum or 
Lysichitons but I don't guarantee a success.

Improvise...

I am an Taylor Holzer I am 14 I am an Aroid collector and i would like to 
add some aquatic aroids to my collection.

i have a large aquarium 55 gallons with some fish. and a smaller one that is 
10 gallons with nothing.
i was thinking about adding Pistia stratiotes, spathiphyllum, and 
Cyrtosperma to my 55 gallon.
in the 10 gallon i was thinking about adding anubias, and cryptocorynes.
also i would like to have a typhonodorum could you keep them in just wet 
soil?

are there any other aquatic aroids i could grow in my aquariums?

any help would be appreciated!
also if you have seeds for these plants i would appreciate them.
i only currently have the spathiphyllum in the aquarium.
