This geranium is recovering from being thoroughly battered by a huge thunderstorm and deluge. I’m about to cut it back so that it can flower some more in the autumn.
Meanwhile, I wonder if anyone can have a go at identifying it. I know it is not G. x oxonianum, though its flower looks similar. Perhaps it could be G. endressii, which is a parent of G. x oxonianum but has no brown blotches on its leaves.
