Blushing unseen?

I doubt many people would include purple dead nettle among the roster of early spring flowers - snowdrop, celandine, violet etc.
It doesn't even have a pretty name. It's defined by what it's NOT (a stinging nettle) although it does belong to the same family along with mint and other square-stemmed plants.

It's hairy, its flowers are tiny and, above all, it's a weed: the seeds have the ability to germinate in any unoccupied patch of soil (read: garden bed) and it spreads rapidly via prostrate stems if not 'weeded out.'

 I was about to tweak the plant  from my veg patch when I decided to take a photo. In close-up the central cluster of hairy purple leaves is quite striking with a modest beauty all of its own.

"Full many a flower is born to blush unseen"  is an anthropocentric statement when you think about it. The flowers of the red dead nettle may escape the notice of human beings but not of bees for which they  are a source of early nourishment; in fact bees harvest both the nectar and the pollen. 
Sharp-eyed herbalists and foragers can also make use of the plant as a styptic and as a snack.
