Can anyone help identifying a plant?
Hi - I have noticed a plant which appears to be growing 'wild' all over the place where I live (Lincolnshire) - along the bottom of people's walls, sometimes through the cracks in the walls, and along the small gaps where the pavement meets people's gardens. It occupies a similar environment as the valerian which grows wild everywhere. It has grey-green foliage and a profusion of small white flowers which have come out in the last week or two. Some of the clumps have grown really quite large, perhaps a couple of foot across, but it is never more than around 10cm tall. I am hoping to find out its name so I can plant some in my own garden. any help much appreciated
