Geranium

Most of my new plants are still getting established. This geranium is one of the few plants put in by the previous owner, that I have allowed to stay, its in full bloom and the bees are happy.  I spent most of the afternoon digging up crocosmia corms.  Its awful stuff if its allowed to spread, which it has. The Wildlife and Countryside Act 1981 makes it an offence to allow it to spread onto other peoples gardens or  into the wild. If anyone has any good tips for getting rid of it let me know.
