    A cool white-flowering hyssop, that produces its slender bottlebrush-like spikes for several months from midsummer. These not only look great (and will help add vertical interest to the border), but they also are sought after by pollinating insects. The subsequent seedheads are a feast for birds.

  • Garden care: Don't cut back the faded flower-stems in until early spring, as they provide interest in the winter months. Lift and divide congested colonies in spring.
