Hebe 'Wiri Charm'. Family Plantaginaceae. Shrub.

Also called Hebe 'Wiri Charm', Veronica 'Wiri Charm'.

A compact evergreen shrub with small, dark green leaves and short spikes of reddish-purple to deep pink flowers. Grow it for its rounded shape, summer colour and year-round foliage in mild gardens; hard frost and cold, waterlogged soil can damage or kill it.

Care

Jobs through the year

WaterApr–May, Sep–Oct, every 14 days
Water established plants deeply only if soil is dry; water young plants more often.
WaterJun–Aug, every 10 days
Water established plants during prolonged dry spells; check containers more frequently.
MulchMay
Apply a light mulch, keeping it away from the stems.
FeedMay
Apply a modest balanced feed only if growth is weak.
PruneApr–May
Once new growth appears, remove frost damage back to healthy leafy shoots.
PruneAug–Sep
Lightly trim after the main flower flush; never cut into bare old wood.
ProtectJan–Apr, Oct–Dec
Not reliably hardy in zones 6–7; overwinter containers in bright, frost-free shelter.
  • Plant in spring in colder districts, choosing a sheltered spot with freely draining soil.
  • Water deeply while establishing, then allow the soil surface to dry between waterings.
  • Apply a light mulch in spring, keeping it clear of the stems.
  • Feed lightly in spring only if growth is weak; avoid heavy feeding and late-season nitrogen.
  • Use a container with drainage holes and protect the root ball from prolonged freezing.

Pruning. Lightly trim after the main flowering flush to remove spent spikes and maintain a rounded shape. Remove frost-damaged shoots in spring once new growth shows; avoid cutting hard into bare old wood.

Through the year

Spring
Plant once severe frost has passed, and water thoroughly.
Mid-spring
Check for winter damage and cut dead shoots back to healthy leafy growth.
Late spring
Apply a light mulch and, if needed, a modest feed.
Summer
Water new plants and containers during dry weather; trim spent flower spikes.
Late summer
Take semi-ripe cuttings from healthy, non-flowering shoots.
Autumn
Check drainage and move pots away from exposed, frost-prone positions.
Winter
Protect plants during severe cold and avoid leaving containers in standing water.

In the garden

  • Plant along the front of a sunny mixed border for evergreen structure beneath taller perennials.
  • Repeat in small groups beside paths or patios for a low, rounded rhythm.
  • Grow in a large container with good drainage for year-round foliage and summer flowers.
  • Combine with lavender, rock roses and ornamental grasses in a sheltered gravel garden.
  • Use in mild coastal gardens where drainage is good and exposure is not extreme.

Garden styles it suits: Coastal, Dry gravel garden, Low-maintenance, Modern courtyard, Pollinator garden and Small-space.

Plant it with: Lavender, Rock rose, Catmint, Salvia, Blue fescue and Thrift.

Wildlife: Flowers provide nectar for bees and other visiting insects. Dense evergreen growth offers small invertebrates shelter.

Problems to watch for

  • Frost damage: shelter from cold winds, protect during severe freezes and wait until spring growth appears before removing damaged shoots.
  • Root rot in wet soil: improve drainage or grow in a raised bed or container; do not keep the root zone constantly wet.
  • Aphids on soft shoots: rinse off small colonies with water and encourage natural predators.
  • Leggy growth or a bare centre: provide more sun and trim lightly after flowering; replace badly woody plants rather than cutting hard into old stems.

Safety

Not known to be toxic to people, cats, dogs or horses. Cultivar-specific information is limited; no particular part is recognised as poisonous, but it is not an edible plant.

Easily confused with

  • Hebe Wiri Mist (Hebe 'Wiri Mist')

    Another compact, small-leaved hebe, but its flowers are white rather than reddish-purple.

  • Hebe Wiri Joy (Hebe 'Wiri Joy')

    Has pink flowers and a similar compact habit; flower colour overlaps, so a reliable nursery label is safer than identifying it by colour alone.

The name

Hebe is named after the Greek goddess of youth.

Propagation. Take semi-ripe cuttings in late summer, using healthy non-flowering shoots and a free-draining propagation mix. Root under cover with gentle humidity; cuttings preserve the cultivar, whereas seedlings may differ.
