Rakai hebe

Hebe rakaiensis. Family Plantaginaceae. Shrub.

Also called Hebe rakaiensis, Veronica rakaiensis, Shrubby veronica.

This compact evergreen shrub from New Zealand forms a rounded mound of small green leaves, with short clusters of white flowers in early summer. Gardeners grow it for its tidy shape, year-round foliage and usefulness in low borders, gravel gardens and coastal planting. It tolerates cool conditions well but needs good drainage and protection from severe winter weather.

Care

Jobs through the year

WaterApr–May, Sep–Oct, every 14 days
Water established in-ground plants only if soil is dry; young plants and containers need more frequent attention.
WaterJun–Aug, every 7 days
Water established plants deeply during prolonged dry spells, allowing the surface to dry between waterings.
MulchApr
Apply a thin organic mulch without covering the crown or stems.
FeedApr
Feed lightly only if growth is weak; avoid heavy feeding and late-season fertilizer.
PruneApr–May
Remove frost-damaged shoots once new growth reveals healthy stems.
PruneJul
Lightly trim after flowering, keeping all cuts within leafy growth.
ProtectJan–Apr, Oct–Dec
In zones 6–7, overwinter in a container under bright frost-free shelter; in mild gardens protect from cold winds and wet soil.
  • Plant in spring in colder areas, keeping the crown at soil level.
  • Water deeply during establishment, allowing the soil surface to dry slightly between waterings.
  • Improve drainage or use a raised bed where winter soil stays wet.
  • Apply a thin mulch in spring, keeping it clear of the stems.
  • Feed lightly in spring only if growth is weak; avoid heavy feeding and late-season fertiliser.

Pruning. Lightly trim after flowering to maintain a compact mound, cutting within leafy growth rather than into bare old wood. Remove frost-damaged shoots in spring once new growth shows which stems are alive.

Through the year

Spring
Plant new shrubs once the soil is workable and severe frost has passed.
Mid-spring
Remove dead or frost-damaged shoots and renew the mulch without covering the crown.
Early summer
Check young plants during dry weather and water deeply when needed.
Midsummer
Lightly trim after flowering, staying within leafy growth.
Late summer
Take semi-ripe cuttings from healthy, non-flowering shoots.
Late autumn
Check drainage and shelter exposed plants from cold winds; avoid pruning.

In the garden

  • Plant along paths as a low, informal evergreen edging that needs little clipping.
  • Repeat rounded shrubs through a gravel garden with ornamental grasses for year-round structure.
  • Use at the front of a mixed border with lavender and hardy geraniums.
  • Grow in a well-drained container to provide a compact evergreen feature on a sunny patio.

Garden styles it suits: Coastal, Dry gravel garden, Low-maintenance, Small-space, White garden and Contemporary minimal.

Plant it with: Lavender, Catmint, Hardy geranium, Blue fescue, Rock rose and Creeping thyme.

Wildlife: The flowers provide nectar and pollen for bees and other visiting insects. Dense evergreen growth offers some shelter for small garden wildlife.

Problems to watch for

  • Root rot in waterlogged soil: improve drainage, keep the crown uncovered and avoid frequent watering of already damp soil.
  • Winter scorch or shoot dieback: provide shelter from cold winds and remove dead growth in spring, not during freezing weather.
  • Leaf spots or downy mildew in damp, crowded conditions: improve airflow, water at soil level and remove badly affected foliage.
  • Leggy growth or poor recovery after hard pruning: give adequate light and trim lightly after flowering rather than cutting into bare wood.

Safety

Not known to be toxic to people, cats, dogs or horses. No particular part is recognised as poisonous, but species-specific safety information is limited; it is an ornamental plant, not a food plant.

Easily confused with

  • White hebe (Hebe albicans)

    Also forms a rounded shrub with white flowers, but its foliage is distinctly grey-green rather than the greener foliage of Rakai hebe.

  • Thick-leaved hebe (Hebe pinguifolia)

    Has noticeably thicker, usually blue-grey leaves, often with reddish edges, rather than the smaller, greener leaves of Rakai hebe.

The name

Hebe is named after the Greek goddess of youth, while rakaiensis refers to the Rakaia area of New Zealand.

Propagation. Take semi-ripe cuttings from non-flowering shoots in late summer and root them in a free-draining medium under humid, frost-free conditions. Seed is possible, but seedlings may vary where other hebes grow nearby.
