I was very pleased with a beautiful Geranium (annual/biannual) I got send by my English friend, she always had in her garden.
It does look like the species Geranium robertianum, but has its flowers more than twice the size, the leaves are the same too, with the difference that the ones of Geranium robertianum have a strong scent and more coarse (hairy) to the feel.
I did do a search but to no avail.. The plants come true from seed so suggests it is a species..
