Hi. It's nice that you are able to get something from your mother's garden.

Just wondering---is it possible that this is not a mini hosta, but one that was growing in a lot of shade . . . and maybe some tree roots? Sometimes hosta don't grow to their full potential if grown in those kinds of areas with limited water supply. Anyways, just had to ask because it's important to know where it was growing before in order to figure out what hosta it might be.

Royal Tiara

I think Oaks has got it. Here‘s a closer pic with scale. Thank you both for the assist!

Royal Tiara is considered a small hosta. It is cute!
