I have a bunch of Rose Campion (Lychnis coronaria) seeds for trade or SASE. I don't have a great picture of these guys blooming, but it was beautiful and they bloomed until the middle of August and very drought tolerant. This is exactly what they looked like during full bloom: http://davesgarden.com/pdb/showimage/159/ I've included a close up of one of the flowers from the plants that I took this morning.
