One of my favorites and is an ancestor of Scarlet Orbit which also produces many, many, many blooms. This is defintely a keeper and part of my hybridizing program.

I received "Charles Johnston" as a bonus plant, and missed the first year's bloom while I was out of town. My neighbor, a professional horticulturist, informed me that it was "a keeper", but forgot to take a photo for me. ;-) It didn't bloom at all the second year for some reason, but for the last 2 years, it has really taken off, and I have to say it was worth the wait. It's a large flower, with a beautiful form with deep red color. My only caveat would be to recommend some afternoon shade so the color will hold up all day. It's not as sunfast as some other reds that I have.
