Summary

This gray-foliaged Mediterranean plant performed best on the three lowest levels of irrigation. Growth differences did not show consistent variation dependent on irrigation. The lavender flower spikes are attractive, though not a striking contrast to the foliage color. The plant appearance is much improved if these are removed after flowering, and the drop in size on the growth charts reflects post-flowering pruning. This unusual shrubby perennial would make a nice addition to a low-water use design for its foliage color and flexible range of lower irrigation levels. The master gardeners did not evaluate this species.
