This charming ground cover is called ajuga. I got that information from naturalist/science teacher/master gardener Ellen. I've written about her so often I think I will dispense with the adjectives from now on. Suffice it to say, she is my go-to gal for all things growing. This week when I look out the library I see this blanket of deep blue surrounding the outdoor classroom. It is a refreshing sight, and makes me think of lavender fields in Provence.
