Charlie, your photos really got me interested in tall garden phlox. I now have 20+ varieties. I have allowed the ones in the backyard to go to seed. Some of the volunteer seedlings have been quite nice. (I am not counting the seedlings in the 20+ varieties). I have been amazed at how well they have populated from seed. Right now my backyard is full of phlox, Rudbeckia nitida,Helianthes Lemon Queen,tiger lilies Angelica gigas, and Eupatorium. I don't do pictures but it is a wonderful sight from my kitchen windows.
I have not seen Nora Leigh in my area, but will certainly add it, if it is available. Shockwave is a beautiful plant and has been with me over 5 years now.
