These are all around the house now.
I used to think this perennial was camomile, but in looking at pictures of that herb, that doesn't appear to be what this is. So, I'm at a loss. The flowers are a very pale blue and the plants themselves are slightly woody. It takes some muscle to remove them from the ground.
Whatever they are, they add a nice splash of color to the green yard.
Beverage: African Rooibos tea
