OK, here's some more info:
"Geranium x cantabrigiense ‘Karmina’ – 'Karmina' Cambridge Geranium appears to be the accepted cultivar name for 'Biokovo Karmina' Geranium. Considered "rhizomatous", it is the result of crosses between G. macrorrhizum and G. dalmaticum. Crosses of those species have become know as the Cambridge Geraniums. The flowers are frequently described as carmine red, but it always seems considerably lighter and move lavendar than red."
