Joan Derifield is a favorite of mine, too. I finally bought Cimarron Rose after seeing so many posting images of it, hope you like it as much as the rest of us
A few more I thought of that are on my favorite watermarked reds list....
Jellyroll Morton, beautiful color, form, big bloom on a tall plant.
Wispy Rays, oldie but goodie, not exactly what you were asking for but it is inexpensive and never fails to stop visitors in their tracks.
Love in a Vacuum, not as pronounced an edge as some of the others previously posted, but the deep saturated color is perfection!
A deep rose red, Carnal Emporium doesn't have a white edge either....
Sorry, guess I'm not much help for adding edges.....but it sure is nice to see all these pretty reds. Dale Hensley and Fighting Fire are both gorgeous!
