I have a hard time telling most of the G. sanguineum cultivars apart. This is one I can't distinguish from the species.

Self-sows gently, and the offspring look the same to me.

I would like some help on getting my cranesbill to bloom again. It's in a very fertile spot with full sun. There is only a litlle crab grass that gets in the clump in late summer and I am very careful to remove that. It does get pretty hot in that spot, I am in zone 5. I only water it in extreme dry periods. Are they heavy feeders? Maybe I need to fertilize it, or maybe the ph is off. Thanks for any help!
