Dear Tom, Eduardo and all Friends,

Here in Florida X. atrovirens is sold VERY seasonally in my 'contact'
groceries, it is sold as 'Malanga amarilla' or 'Yautia amarilla', and is
very popular w/ folks from the Dominican Republic. It has a
dark/blackish-skinned HAIRY (roots) rhizome, usually the same thickness
throughout, usually short and relatively thick, it is cut flush at the
growing side, 'healed' at the bottom, looks more like a Colocasia rhizome,
and is quite unlike the other flask-shaped rhizomes ("chubas"!!! :--)>) of
the other Xanthosoma sps. commonly sold here in S. Florida. As Eduardo
said, it has a strikingly colored orange/yellow flesh, and this has a corky,
lighter colored layer about 1/8" thick between the orange flesh just under
the black skin. The flavor when cooked is like a mixture of peanuts and
corn flour. The plant grows with the blade`s sinus full to the joint, very
unlike other Xanthosoma sps. I have grown and seen. The last I grew had a
silvered 'sheen' to its leaves, VERY attractive.
I`ll ask my Cuban/Dom. Rep. friends here where it is commonly grown, if I
had to guess, I`d say it is commoner in the Dom. Republic. We did NOT have
it in Trinidad, and my Cen. American friends do not know it.
Before I forget, Deni Bown refers to this yellow fleshed one as X.
atrovirens, but she also calls the Xanthosomas, one w/ the var. colored
'deformed' leaves w/ the 'cups' on the leaf-tips, AND the all-green w/ the
little "labias" on the underside of the leaf blades, X. atrovirens, I do not
believe this is correct.
Hope this helps!

Thanks for your detailed information. I didn't check the colour of the
rhizome flesh before planting....Does someone know if it is likely that the
plant forms new tubers in pot culture (have put it in a huge pot) and how
long this would take? I live in Germany and keep the plant indoors during
winter (warm and bright place). Thanks for info.

Dear Frank,

Based on my observations of the rhizomes offered for sale here in West Palm
Beach, Florida, it would appear that this species does not produce the
flask-like off-sets/rhizomes/tubers as do the other species of edible
Xanthosomas, and that the portions offered for sale are lower portions of
the main rhizome, NOT off sets, and the cultivation of this species, like
some species of Colocasia ('dasheen-types") depends almost soley on
re-planting the upper growing-point portion of the plant. Therefor I
believe that it may not produce as many off-sets/propagules as the other
species. I did see a few propagules that were produced off the main
rhizome of my plants, this took several months. I tried twice to grow this
plant in a 3 gal. pot to try to get it to bloom, but it was such an
attractive plant that both times it was stolen by laborers!
The Best,
