I’m sure most of you are familiar with Herb Robert (Geranium robertianum), a very common wildflower that can found everywhere from pavement edges to woodland rides, from the southern coasts of England and Wales to Scotland’s northern isles (you can see the 2020 Plant Atlas distribution map here).

What I had never seen until very recently was the attractive white-flowered variety of Herb Robert, this one growing alongside a well-trodden path come side road in Cardiff Bay. I don’t think this is a native variety as the Plant Atlas mentions that ‘White-flowered forms, in particular, may be deliberately grown in gardens and sometimes escape’. Though this location is surrounded by multi-storey apartment blocks, I guess the seed must have blown in from somewhere.
