This is a great plant that keeps getting bigger and bushier with each year. The blue colour is amazing from a distance and bees find it irresistible.
Actually, I'm not sure if anyone has had this experience, but I keep finding seedlings where the arching branches have flowered and obviously set seed. These are not root suckers, because when I pull them, they come out with an independent tap root. I surely didn't expect it from this plant. It is a discreet colonizer though. There are just enough plants to give away to friends.
