I found a strange plane growing in my garden, not sure if it's a weed
or not so left it for the moment.
Can anyone tell me what it is?

I think it's Geranium palmatum, the hardiest of the three large Geraniums
which does seed itself about. It could be G. maderense but you would be very
lucky for it to self seed.
Nice plant either way.
