I have to agree with Janet,
@plantladylin, yours doesn't look like A. maculata to me either. The leaves look too long and narrower at the base as she mentioned. I have photographed it in two botanical gardens, a few nurseries and several other gardens and have one in my garden. As Marilyn noted from wikipedia in the comments section, it can be variable but one thing that is distinct are the H shaped spots, I think that means they are closer together as my photo show, that's how I interpret it anyway, I may be wrong.
Yours seem more scattered.
