  May I have your opinion please

Greetings IAS Friends,

Attached are 2 pictures of an Aroid

I "rescued" late last fall from a client's

Planter. The cold had withered the leaves,

I was not able at the time to determine what the

plant was.

I suspected it was an Aroid, so I took off all the

dead roots and stems, repotted

with new media, watered in, and over wintered the

the pot in a cool location.

In may the new growth emerged, and I bumped up

the plant several times. Here we are in August, with

great growth and habit. May I ask Other Forum Members,

for your opinion as to an I.D. ?

Thank you all in advance,

Michael Kolaczewski

It looks to be Xanthosoma atrovirens possibly robustum. Both are very
large growers in hot humid conditions.

Looks a bit like my Calocasia x inodora but I am NOT an expert

Dear Michael,

For sure it is Xanthosoma,

species maybe atrovirens (the short, rounded posterior lobes and the glaucous leaf colour makes me think so).

Dear Michael:

It looks like Xanthosoma robustum to me.

Brian, Kyle, Marek, and Tom,
Thank you all, very much for your help.

As I mentioned earlier to Lariann,

This plant has done well outdoors this growing season.

In fact, each leaf that emerges, is larger than the previous one.

Chicago has been hot & humid this summer.

No flowering as of yet, but when this plant does,

I will be sure to photograph it.

Again, thank you all, your input is much appreciated.

Dear Michael,

I agree with Tom. Positively is Xanthosoma atrovirens, the
typical form. In fact, the it will become the only because all other “X.
atrovirens” varieties and forms are different species (to be described/combined

Very best wishes,

Greetings Marek,

Thank you very much Eduardo, and again

everyone else, with you earlier responses.

Sorry to get back to you days later, I have

been busy "gardening" here and there.

As you all have shown me, Xanthosoma atrovirens

is what I have. My tropical taxonomic skills are very much

in the fledgling stage, and will be for some time.

I have taken the time of course, to look over this plant

through Print and the on line resources, and I studied

the descriptions, and looked at many photos.

I am planning to propagate this plant asexually later

this season, and will hopefully have successful results

to share with you later.


Thank You, dzien kuje, muchas gracias !!!
