I recently acquired an alocasia polly from my local home depot for a good price. The plant was in good shape except for the curling/twisting of the ends of about half of the leaves. It was like this when I bought it and didn't think much of it but want to make sure it's not a bigger issue. The leaves feel firm, are a dark green and have no visible discoloration spots or bugs anywhere. This goes for the curled ends as well. It could be that whatever the plant grew in, something was in the way of the leaves but I don't know. I currently have the plant on a short bench about 2 feet from a green light with an output of 16 umol/second. Any help would be appreciated.

All of these Poly's are tissue cultured. Sometimes they turn out wonky. Yours is a wonky one.

Thanks! I figured it probably wasn't a disease/pest/fungus but just wanted to make sure.

Poly is a weird plant to begin with. Its a sanderiana hybrid that, from the data I have read, probably has some chromosomal mismatching. It was originally named Poly because the folks who discovered it thought it was a polyploid. That name then got corrupted later on into 'Polly'. But the correct name is 'Poly'. From what I have read in the past, when they tissue culture plants most of the time they mix samples from more than one plant. Sometimes some plants turn out a bit wonky. Sometimes, this results in a plant or 2 that are different enough for them to declare that they are a new cultivar, and they will select that plant out and tissue culture just it over successive generations to see if whatever they decided was different enough is stable, and they will patent that and market it. This is what happened with Alocasia reginula. The plain species that we used to grow many years ago was just Alocasia reginula as it was collected in the field. Then a TC company felt that they had a newer better plant and patented a cultivar A. reginula 'Black Velvet'.

Thanks for the additional information, it was an interesting read. I wonder if the raven ZZ plant was created in a similar fashion, a plant on my wish list. I recall reading somewhere that polyploidy happens quite frequently in plants, I'm sure quite a few interesting "accidents" result from that.

If you want to know the origins pf Alocasia 'Poly', I can fill you in. Alocasia 'Poly' is also known as ALocasia x Amazonica. But this is a misnomer. It is NOT from the Amazon and has never been observed in a tropical rainforest in the wild, anywhere. This plant is a hybrid, most likely between Alocasia sanderiana and Alocasia Loweii. Aroidists John Banta and Julius Boos traced its origins to a nursery in Miami in the 1950's called Amazon Nursery, owned by a man named Salvadora Mauro. He named the plant after his nursery... Alocasia amazonica. Poly was thought to be a stable hybrid (polyploid) by the owners of SilverKrome nursery, the Rotolantes. This plant is not a species. It is a hybrid. With an interesting history none the less
