I doubt this is it, but my first thought was, boy that looks like my faded out Korth Royal Banner. Mine faded out in the high 80's. For some reason I don't think you have those kind of temperatures. Here's a picture of mine:

I have no idea what it is. The colors and the edge make me think of Lambertsons. Could it be a Stone Palace cultivar? It may be one you received in error. I had so many mistake plants sent over the years.

Debra

I'm sorry, no idea Sherry.

Sherry,

I would have to agree with Debra as my first thought was a Lambertson introduction. The colors and the edge are what made me think of his intros. You could go to the registration site and look at all of the Lambertson introductions.

Thanks David and Debra, looked at the registration site. I found a possible match but seriously doubt I would get it by mistake, seems a bit obscure. I would not order a Lambertson, I only have one that likes it here, have lost several. It looks like Violet Headed Hummingbird but will have to compare future blooms to even consider it a match. My guess is it will always be a mystery.
