Earlier this year in the German town of Wittlich I noticed a Geranium species I had never seen before. The plants grew in a lawn together with Bellis perennis and other common species.
I asked the owner of the place whether he was cultivating the species as an ornamental plant. He said the plants had already been present when he had bought the house years ago. As he liked the species he did not prevent the spreading of the species.
The species was keyed out in Rothmaler vol. 5 as Geranium pylzowianum from China.
My question is whether my identification is correct and whether it was seen growing wild in Germany or elsewhere in Europe.
