I am not sure what this is - it could he Hemp Nettle, or not. I can't believe how hairy it is (try large). Every part of it is hairy except the stem which is more prickly. It is among the grasses at the edge of the field behind our house, and attracts butterflies.

An odd day weatherwise - a few bright hot sunny spells, and lots of periods of heavy-looking cloud as well. Not particularly warm for most of the time but dry.
