Hebes divide by leaf, and the leaf tells you how cold a winter it will survive. Small-leaved, tight, grey-green kinds are tough enough for anywhere; the big glossy-leaved ones with long flower spikes are the ones that get killed in a hard winter, having looked perfect for five mild ones.

They also dislike being fed. Rich soil gives soft growth that flops open in the middle, and a lean, gritty, sunny spot gives the dense dome the plant is bought for.

Hardy alpine/whipcord hebe

This is the hardier, small-leaved end of the genus — it doesn't need the winter shelter routine that the large-leaved tender_large_leaved group does.

Part shade Water: average H4down to −10 °C 30–60 cm tall · 40–60 cm wide In a pot: yes
Flowering · UK
Flowering · Northern Italy
Flowering · Central Italy
Flowering · Southern Italy and islands

Care

Light

Tolerates open, exposed and coastal sites well — one of the hardier, more wind-tolerant shrubs in the KB.

Water

Once established.

Soil

Free-draining soil of low to moderate fertility; winter wet is more of a risk to this group than winter cold.

Pruning

Trim lightly in late spring, before the new season's flowers appear, to keep tight, compact mounds; avoid hard pruning into old wood, which many types won't reshoot from.

Feeding

No feeding. The small-leaved alpine hebes want lean, sharply drained ground — fed, they grow loose and leafy, flower less and come through winter worse.

Propagation

Semi-ripe cuttings in late summer root easily in gritty compost. Since old plants become bare and woody at the base and cannot be cut back into old wood, replacing them from cuttings every few years is standard practice.

Common problems

Winter waterlogging

How to spot it. Blackened, mushy growth at the base after a wet winter.

What to do. The main risk for this group is poor drainage, not cold — improve drainage or raise the planting position.

How to spot it. In humid conditions.

What to do. Improve airflow.

How to spot it. On new growth.

What to do. Encourage predators.

Tender large-leaved hebeShrubby veronica, Large-leaved hebe

Tender large-leaved hebe

Check the specific hardiness of the named cultivar before planting in an exposed spot, and have a winter shelter plan ready in cold gardens — this group is considerably less cold-tolerant than small-leaved alpine hebes.

Flowering · UK
Flowering · Northern Italy
Flowering · Central Italy
Flowering · Southern Italy and islands

Care

Light

A sheltered spot, ideally against a warm wall in colder gardens.

Water

Once established.

Soil

Free-draining soil of low to moderate fertility; dislikes waterlogging, especially in winter.

Pruning

Trim lightly in late spring, before the new season's flowers appear, to keep compact; avoid hard pruning into old wood, which many types won't reshoot from.

Feeding

At most a light spring feed on poor soil. As with the alpine kinds, soft well-fed growth is what the first hard frost destroys, and these are the less hardy of the two.

Propagation

Semi-ripe cuttings in late summer, overwintered under cover. Take them every year as insurance: a large-leaved hebe is the plant most likely to be lost in a genuinely cold winter.

Questions

Alpine hebe: is it hardy?

H4: Hardy through an average UK winter. It survives down to −10 °C.

Can it grow in a pot?

Hardy alpine/whipcord hebe: Does well in troughs and pots, though it's hardy enough for open ground in most UK gardens. Tender large-leaved hebe: A sensible choice in colder gardens, since it can be moved to a sheltered spot over winter.

Alpine hebe: when do you prune it?

Hardy alpine/whipcord hebe: Trim lightly in late spring, before the new season's flowers appear, to keep tight, compact mounds; avoid hard pruning into old wood, which many types won't reshoot from. In the calendar for UK, pruning falls in May. Tender large-leaved hebe: Trim lightly in late spring, before the new season's flowers appear, to keep compact; avoid hard pruning into old wood, which many types won't reshoot from. In the calendar for UK, pruning falls in May.

Alpine hebe: when does it flower?

Hardy alpine/whipcord hebe: In the climate of UK it flowers in June–August. Tender large-leaved hebe: In the climate of UK it flowers in July–October.

When do you feed it?

Hardy alpine/whipcord hebe: No feeding. The small-leaved alpine hebes want lean, sharply drained ground — fed, they grow loose and leafy, flower less and come through winter worse.
