Nice hardy Hebe for us here in the PNW as this hails from the alpine and subalpine areas of the drier mountains on New Zealand's South Island.  A low creeper to just 8" high, the olive-green leaves are quite good but it really gets its groove on when it blooms as the white flowers contrast with the near-black stems.

This has been a fantastic Hebe in our garden handling our worst winters with aplomb.  A low 20" x30" evergreen shrub with narrow gray-blue leaves and lots of small white flowers for at least 2 months June-August.  Ours looks great planted with Mertensia maritima and it is perfectly ok to steal this planting combination.
