I believe this is a Hyssop, but it sure looks a lot like a Germander. One time I asked one of my favorite nurseries, Down to Earth in Eugene, Oregon, and they looked it up on the internet, and still it was hard to be decisive. The final conclusion was that it was Hyssop, but only by a nose.
Bumblebees, the ones with yellow stripes across their black bodies, just love these flowers. The bees never bother me, they know what they are interested in.
These perennials are so easy to grow. When I remember to cut them back in the dormant season, they come back so strong the next summer. The cut flowers make a beautiful addition to flower arrangements. If you wait until late winter or spring to prune this plant, you give some time for the spent flowers to go to seed. The baby plants are so sturdy and reliable, they are worth the wait to watch them grow.
