thanks, Stefan. It is definitely a dwarf variety and has bloomed in mid to late summer, so it fits the 'flame' description in the 'Perennials' link very well, and 'flame' is also what was on the tag. It just seems to be the color that was off, as it's much lighter than the 'coral' color. My guess is there were a couple different 'Flame' varieties sitting next to each other in the nursery, and maybe a tag got switched by accident somehow.
The photos in the 'perennials' link do not look much different for pink flame versus light pink flame!
I'll need to go out and look at it again and get another photo of it...
