Alpine Enchanter's Nightshade

Spent some time poring over wildflower books and peering through my 10x loupe and measuring and taking photographs of this plant this morning while the other members of the household snoozed on. 'Enchanted' to identify it as Alpine Enchanter's Nightshade (Circaea alpina). It's growing NE of the holding wall on the back terrace opposite the back door. The double petal flower measures 6mm across.

I did take some shots of the whole area where the plant is growing but the light was too bright so I'll try again when the light is gentler.

Here are three – the one taken in bright morning light and two in the shade. The last one is from above.
