Geraniums in my Garden is nearly ready for publication. When I gathered the photos, I noticed one missing, G. oxonianum f. thurstonianum, at least none from the garden. The unusual flowers are worth the wait.
I may have found the cultivar name. In the RHS Plant Trials and Awards pdf online, I found a photo of G. oxonianum f. thurstonianum ‘Armitageae’. The flowers look exactly like mine. So lovely.
