Are you sure you don't mean Geranium phaeum 'Samobor'? If so, this species of hardy geranium is native to European woodlands and prefers full to part shade. If grown in very much sun, it will need evenly moist soil that is not allowed to dry out. Likely not a suitable cultivar for areas of high summer heat and humidity.

ps - in my garden, this plant self-seeds like a pack of rabid monkeys, to the point of being nearly a pest.
