  xanthosoma mafaffa
From: Tony Avent tony at plantdel.com> on 2001.10.02 at 12:44:20(7561)
Aroiders:

I'm trying to find anyone that has overwintered Xanthosoma mafaffa, the
cultivar sold as 'Aurea' or 'Lime Zinger' outdoors at any temperatures
below 32 degrees F. Any help would be appreciated.

Dear Tony,

I will be very interested in hearing the 'end' results of this
survey---Xanthosoma 'mafafa' (in fact all species of Xanthosoma) are
heat-loving plants, but who knows what extremes of low temps they might
withstand, as they do grow pretty far south into southern S. America
(Eduardo???). Somehow I suspect that you will find that the leaves will
not withstand much below say 50 degs F., and the plant will be killed by
wind with temps below this, and frost will kill the rhizome.
Please let us know the results of YOUR attempts, but only after 'you kill it
yourself---at least three times!'

Cheers,

Julius

Hi Tony,

Well, the plant you cited (i.e., the Xanthosoma "Golden", "Aurea" or
"Lime Green", erroneously known as X. mafaffa) is a heat-lover indeed. My
plants almost died here in Sao Paulo (temperatures during winter usually
reach 8 oC) and now they are trying to recover. I am not an expert on
overwinter plants (I have never seen real snow in my whole life!), but I do
not believe that these plants are that hardy. Their rhizomes are somewhat
tender and proned to desiccation.

Very best wishes,

Eduardo.

Julius:

We tried Xanthasoma maffafa 'Aurea' outdoors back in 1995. That winter we
reached 0 degrees F, and the plant was mush. The foliage was fine up until
frost. I guess we should try again now that we are having global warming.
You've got to look at the positive side of every issue...xanthosomas will
be hardy for everyone soon!

Eduardo:

You mention that Xanthosoma maffafa is erronously known as such, but you
don't mention what it should be correctly known as...any help with a
correct name would be most appreciated. The only cultivar name for this
plant that adheres to the nomenclature code is Xanthosoma 'Lime Zinger'.

Dear Tony,

Good luck! (as the corus of the song 'Dream Lover' by the Everly Brothers
plays in the back ground) I don`t think that Xanthosomas can or ever will
withstand near freezing temps.---better chance of penguins living in Lk.
Okeechobee or Elephants at the N. Pole, but we can try, correct?!
These tropical plants SEEM fine with a short 'blast' of low temps., but IF
they don`t turn to mush right away, the cold damage is horrific after a few
days/weeks, the tissues die, and then they die.
Hope to see you soon!

Julius

Dear Tony,

I didn?t mention it just because I could not find a name for it! (That?s
quite simple...) I am completing an article about the cultivated Xanthosoma
and this is one of the "species" that doesn?t seem to have a Linnean name.
In fact, I do not know if it is a natural species. I am presently calling
Xanthosoma "Lime Green" or "Golden" or "Aurea" or "Lime Zinger" or whatever.
The only thing I know is that it doesn?t seem to be X. mafaffa, because of
vegetative and floral differences. In fact, true X. mafaffa is an elusive
species that doesn?t seem to be common in cultivation no more. It is
possible that this golden Xanthosoma is one of the species from the X.
atrovirens complex. I am still checking some aspects on it. By now, it is
better to keep the name exactly like it is.

Very best wishes,

Eduardo.

I hope you will keep up posted as your research yields results.

Wooly mammoths lived quite close until either humans hunted them out of
existence or it got too warm.
