my lawn has been taken over!

Thanks all. Yes, I think it is a hardy geranium, and it seems intent on colonising every space going in my garden! Personally I rather like it - my lawn looked like a bit of a wildflower meadow last summer. I think mainly I feel gulty because all the other houses in my 'row' have grass lawns! - though that may not be true once all this is over...

Could be a hardy geranium. There is one very small one with pink flowers. It acts like ground cover if you let it and will quickly spread. Or there is a slightly bigger purple flowered one. If you want to get rid of it there will be lots of rhizomes to pull up. But it is pretty as it is. (Unless it is something else altogether)!

Yes, I'm pretty sure it's one of the hardy geraniums.

It looks a bit like one of those geranium type plants.

It looks nice and will probably need less watering than grass in the hot weather.

"wild lawns" are very in now.
