Neutral coriaceous On Nov 22, 2014, coriaceous from ROSLINDALE, MA wrote:

Flowers a brilliant carmine-magenta with a black center and veins, slightly larger than typical.

Requires sharp drainage. This is a plant for the rock garden rather than the border.

Said to be less robust/hardy than 'Giuseppe'.

This is an old cultivar possibly raised by Georg Arends in Germany in the 1930s.

Geranium cinereum ssp. subcaulescens is now generally treated as a separate species, G. subcaulescens.
