Hebe masoniae (syn Hebe pauciramosa subsp masonae) is an evergreen, bushy shrub, which grows to about 20 in (50 cm) high. The leaves are broad spear-shaped, 0.24–0.35 in (6–9 mm) long, sharply keeled beneath. Clusters of white flowers in summer. This hebe is hardy in the UK.
Hebe masoniae is found in tussock grassland or scrub in the mountains of western Nelson, South Island, New Zealand. It was regarded as a subspecies of Hebe pauciramosa, but has been separated on the basis of leaf size and shape.
