We have a plant in our garden - actually lots of it - that is just coming to the end of flowering. It is around 2ft tall, with bright magenta flowers, 5-petalled, around 1" across, and silver grey foliage.
Sorry, no pics, haven't got into doing that.
It seeds fairly freely round the garden.
I'm never sure if it is annual, and I should just pull them out once they have seeded, of if they are perennial and I should cut them back. So ID would be useful if anyone has this plant and knows what it is.
Thanks!
