The parents, Hebe speciosa and Hebe elliptica are both found naturally in New Zealand with the latter also inhabiting southern South America and the Malvinas/Falkland Islands.

It grows well on the coast and produces much of the summer a constant display of fragrant violet/blue flowers fading almost to white. The flowers are sweet-smelling, and are much visited by bees; it has been known to be continuously in flower for over 2 years at a stretch. It grows to a height of 1.5 to 2m with a similar spread.
