From Kenner, La. I have a relatively large plant outside in a pot. It has large whitish leave with green edges.
Our resources here at PHS are concentrated on plants found in the mid-Atlantic region, so we are not able to attempt plant identifications from other parts of the country.
We suggest you contact your local county extension Master Gardener program. Master Gardener volunteers work through their county extension services to give plant information to people in their communities.

Good luck with your research.
