Herb Robert ( Geranium robertianum )

Another wet day!  I might get used to this, but I doubt it.  So it was late afternoon when I wandered into the, by then dry (ish) garden looking for a blip.  Among the things I shot was this little Herb Robert, they have always been rather a favourite of mine.

As the scientific name suggests it is a member of the geranium (cranesbill) group.  Having had a read up about it it seems its scientific name hasn't changed in about 500 years.  That must be a record because currently everything plant or animal seems to be having its scientific name changed with monotonous regularity.  White varieties have been used in gardens for centuries.
