It is time to get out the lawn mower, but, well! The grass grows, but also lots of flowers. Common Bugleweed (Ajuga reptans) colonized the lawn. Every angular and rigid stalk carries tens of little blue flowers.
The blue is accentuated by dark bracts below every ring of flowers.
Seen from nearby it is really hairy! In every flower grow four stamina, a pair of long ones and a pair of short ones. Yellow anthers hover above the flowers. Irresistible for pollinating insects.
