Tropicals & Tender Perennials: Need advice - Is there a "mannerly" elephant ear?, 1 by LouisianaSweetPea

I liked the look of the yard in the picture, below, and want to create a similar setting in my own yard. I was told that the large, elephant-ear-looking plants might be Xanthasoma sagittifolium or an alocasia.

After reading about the Xanthasoma and similar plants, I am worried that these things, although beautiful, might be invasive.

Not being educated about elephant-ear-type plants, I am asking if anyone knows of a "mannerly" plant of this sort that will not jump out of the flower bed and take over the yard?

Thanks! -- Jean
