I always wondered if anyone grew Rose of Sharon - I don't think you could kill that with a stake and holy water.... Not sure if the leaves would reduce, but the blooms would be pretty spectacular.

I've seen some half-decent examples and there's some discussion on bnut about the species. It seems not ideal but there are certainly worse species that people try. I have a couple that I nabbed for a few dollars on fall clearance that I intend to mess with.
