I have several, but the only one that I can name for certain is the G. maculatum. that I dug out of a roadside wood that was about to become a gravel pit. I have it planted in front of the house with some Jacob's ladder that I found in the same place. One other is, I believe a G. striatum, pink with darker stripes. That blooms all summer long for me, starting a bit later in the season. I have two that resemble "Splish Splash" and "Johnson's Blue" and a little one that flowers a strange greyish pinky white.
I planted the one with the long bloom season with some Dicentra exima under the sorrel tree and I let them shoulder each other out - both rather prolific spreaders. The others are sort of here and there rather than in any specific place. I am very random, I'm afraid.
