Dear All,

Can somebody help me with variegated Araceae?
Because I do not know how variegation starts. Are there some viruses or
chemicals which can induce variegation? Can occure variegation by
micropropagation? How often?

Jani,

The only aroid species I know very much
about are Anubias and Cryptocoryne. These are definitely moisture-loving
plants and would not appreciate dryness.

There are many varieties of each and
these vary in requirements. Many of the Anubias are large plants and can
easily get too big for an aquarium. Just this past weekend I was visiting
a friend with an Anubias with leaves easily half a meter high, with the
leaf blades completely above the water line. The one well-behaved Anubias
that can be kept neatly submerged in a typical aquarium is the one called
Anubias barteri nana or just Anubias nana. This last species is also very
tough and resists even plant-nibbling fish. In my tanks it reaches a maximum
leaf length, including petiole, of about 20 cm. More typically it is half
that. Its only drawback is that is grows slowly. But it is easy to grow
and should be readily available from any aquarium club and many commercial
stores.

Cryptocoryne are generally more challenging;
some may say a lot more challenging. While many will perform satisfactorily
submerged in water, many require an "emerse" culture, meaning
with their leaves above the water line and their roots wet. For a quick
reference I recommend the site maintained by Jan Bastemeijer of the Netherlands.
There is much information there. He may still be a member of this list.
His site can be reached at:

.

Beyond that it would be well to make
acquaintance of an aquatic plant fancier who lives near you. In fact, if
you contact Jan he can probably put you in touch with one of the members
of the European Crypt society.

Good luck,

Ted.

Ted,A couple of years ago I received rhizoms of different anubias (gigantea, afzellii and three unidentified) from one of the experts in the HBV (Vienna University, Botanical Gardens). They had been collected in a dried out riverbed in Eastern Africa and thenlegally imported into Austria for research work. The original plants are kept in water containers, the rhizoms permanently submerged and the leafs growing out up to more then a meter. I was asked, to try to grow them in pots in a sandy potting mix and not submerged (!), but regularely watered. All of them are doing extremly well under this conditions and I think, some species have a high potential to perform as hardy pot plants. In winter I do keep them indoors (not necessarely in a greenhouse
) and in summer I put them outside in a shady spot.Unfortuantely I had a drawback some weeks ago, caused by some neglect re. watering. It was my fault. But meanwhile all of them do recover and show lots of new shoots.So I think there is much more investigation required, to make these wonderful, decoartive plants useful, notonly for aquarium enthusiasts.Helmut Reisenberger Von: Discussion of aroids Gesendet: 21.12.06 19:18:10An: Discussion of aroids Betreff: Re: [Aroid-l] variegata aroids + a lots of questions + contactsJani,The only aroid species I know very muchabout are Anubias and Cryptocoryne.

Helmut,

This is a very interesting anecdote
regarding Anubias hardiness. See also my note to Jani. The only other observation
is the probably extreme hardiness of the rhizome. The plants can probably
sacrifice any leaves while hunkering down in the rhizome to await better
times when water is more available. I don't know how durable the rhizomes
might be for cold. I have placed Cryptocoryne rhizomes in a refrigerator
for weeks (what is that?, 45F/8C?, something in that range). What happens
to these rather delicate plants is that the existing leaves melt, but new
leaves come readily. Who knows? Maybe Anubias can survive as a protected
rhizome down to near freezing. Maybe some of the Florida people can experiment.

P.S. I would be careful in Florida.
I think Anubias could be an invasive species. There are reports of colonies
of the Asian Cryptocoryne naturalized in Florida and Texas.

Ted.
