Hebe Red Edge Shrubs (Veronica 'Red Edge')

What is Hebe Red Edge?

Hebe Red Edge, also known as Veronica 'Red Edge', is a compact evergreen shrub with small, blue-grey leaves outlined in red. The narrow red margins become stronger in winter, bringing a welcome touch of colour to borders and pots through the colder months. Short spikes of pale mauve flowers appear in summer, gradually fading to white above the rounded foliage.

Hebe Red Edge naturally forms a small, rounded bush that needs little pruning to stay tidy. It fits comfortably at the front of a border, among stones in a rock garden or in a generous patio pot. The evergreen leaves keep these smaller planting spaces looking settled through winter, with flowers adding interest in summer.

Why choose Hebe Red Edge?

The changing leaf colour is one of the pleasures of growing Hebe Red Edge. Its blue-grey foliage carries a delicate red outline through summer, which deepens as temperatures fall. Even in the middle of winter, the little rounded leaves provide colour near paths and entrances. In summer, pale mauve flower spikes bring bees and other pollinating insects into the garden.

Its naturally compact growth makes Hebe Red Edge easy to maintain. A light trim after flowering will usually keep any stray shoots in check, without cutting into older wood. Plant one beside a doorstep, set several along a path for a low informal hedge, or divide a pack between patio containers and gaps at the front of a border.

Eventual height, spread and growth rate

Hebe Red Edge typically grows to around 60cm tall and wide, although mature plants may reach 75cm in favourable conditions. Growth is generally slow to moderate, with around 10 to 15cm of new growth possible in a year once established. Occasional light trimming helps keep the shrub compact without spoiling its natural shape.

This relatively slow growth is useful where space is limited, particularly beside paths or in narrow borders. For groups of individual shrubs, leave around 50 to 60cm between plants. This gives the branches room to spread and allows each plant to develop its naturally rounded outline.

How to use Hebe Red Edge in your garden

At the front of a mixed border, Hebe Red Edge looks particularly attractive beside low-growing perennials and plants with fresh green foliage. Groups of three or five can form a low, informal flowering hedge along a path or driveway. The small red-edged leaves give the planting a clear outline, while the rounded branches keep the effect soft and natural.

In containers, Red Edge works well on its own or combined with trailing plants that soften the pot rim. Choose a pot with good drainage holes and use a loam-based compost. A sheltered patio or balcony position helps protect the evergreen leaves from cold, drying winds. It also suits coastal gardens, tolerating salt-laden air better than many shrubs.

Choosing a size

Hebe Red Edge is supplied as young shrubs in 9cm pots, with packs of 2, 3, 4 or 6 plants available. A pair works well in separate containers, while packs of 4 or 6 are useful for planting a short informal hedge or filling several spaces along a border.

All four options contain the same 9cm pot-grown Hebe Red Edge plants, so you can choose the quantity that suits your planting space. Give each shrub enough room to develop and water regularly during establishment, especially when growing in containers.

When and how to plant

Pot-grown Hebe Red Edge can go into the garden throughout the year, provided the ground is not frozen or waterlogged. Spring and early autumn are particularly good planting times, with milder weather and generally more reliable soil moisture. During hot, dry spells, newly planted shrubs need closer attention to watering.

Water the plant thoroughly while it is still in its 9cm nursery pot. Dig a planting hole wider than the rootball but no deeper, keeping the top of the compost level with the surrounding soil. Backfill, firm gently and water well to settle the soil around the roots. For patio containers, choose a pot with drainage holes and fill it with a suitable loam-based compost.

Spacing guide for hedges

If you are planting Red Edge as a low informal hedge, space the plants about 50cm apart. This allows the branches to spread towards neighbouring plants and gradually form a continuous line of evergreen foliage. How quickly the gaps close depends on growing conditions and the size of the young shrubs.

For a single row planted at 50cm intervals, the following quantities will cover common hedge lengths. Allow space at either end according to where you want the hedge to finish.

Watering and feeding

Keep the soil or compost consistently moist during the first growing season while roots establish. Check container plants more often, as pots dry out faster than garden soil. Water at the base rather than over the leaves, and allow excess water to drain freely. Cold, waterlogged compost can damage the roots over winter, so keep containers sheltered from prolonged rain where possible and raise them on pot feet to help excess water escape.

Feed lightly in spring with a balanced, slow-release fertiliser suitable for shrubs. Avoid high-nitrogen feeds, which can encourage soft growth that is more vulnerable to cold damage. A mulch of well-rotted organic matter around the base in spring helps retain moisture and suppress weeds, but keep the mulch clear of the stems.

Trimming calendar

Hebe Red Edge needs very little pruning. Once flowering has finished, usually in late summer, snip off faded flower spikes and shorten any shoots that spoil its rounded shape. Make cuts just above healthy leaves, keeping to the leafy growth rather than cutting deep into bare, older stems. Hebes may struggle to regrow after hard pruning.

A simple trimming schedule keeps the shrub neat:

• Late summer (after flowering): Lightly trim to shape and remove dead flower heads.
• Early spring: Check for winter damage and remove frost-affected shoots once the worst cold has passed.
• Ongoing: Pinch out the tips of young plants in spring to encourage bushier growth.
