Best Evergreen Shrubs for Year-Round Structure

Why Evergreen Shrubs Matter

Evergreen shrubs are the skeleton of a garden. They provide structure, colour and shelter all year, even in the depths of winter. Without evergreens, a garden looks bare and dead from November to March. With evergreens, the garden has shape and interest through every season.

In the Chilterns, where winters are cold and the chalky soil can dry out even in winter, evergreen shrubs are particularly valuable. They provide shelter for wildlife, screening for privacy, and a backdrop for spring bulbs and summer perennials. A well-placed evergreen shrub can transform a border from a summer-only feature to a year-round feature.

The trick is to use evergreens as the structural plants (about 30 to 40 percent of the border) and fill in with deciduous shrubs and perennials for seasonal colour. Too many evergreens and the border looks static. Too few and it looks bare in winter.

Best Evergreen Shrubs for Structure

These shrubs provide the backbone of a year-round garden. Plant them first, then fill in around them.

• Photinia Red Robin, bright red new growth in spring, evergreen, can be clipped into a hedge
• Choisya, glossy green leaves, scented white flowers in spring, rounded shape
• Pittosporum, small wavy leaves, good for clipping, looks good all year
• Mahonia, spiky leaves, yellow winter flowers, architectural
• Viburnum tinus, clusters of white flowers in winter, dense evergreen

Best Evergreen Shrubs for Scent

Scented evergreen shrubs are a winter essential. Plant them near paths and doorways so the scent reaches you in the coldest months.

• Sarcococca (sweet box), intense winter fragrance, plant near the door
• Choisya, orange blossom scent in spring
• Daphne, scented winter flowers, slow-growing
• Edgeworthia, scented yellow flowers in winter, unusual
• Mahonia, lily-of-the-valley scent in winter

Best Evergreen Shrubs for Shade

Shady spots are common in Chiltern gardens, particularly under mature trees and on north-facing boundaries. These evergreens will thrive in shade.

• Mahonia, thrives in shade, architectural leaves
• Sarcococca, tolerates dry shade under trees
• Skimmia, glossy leaves, red berries on female plants
• Fatsia, large architectural leaves, tropical look
• Aucuba, spotted leaves, tough as old boots
• Holly, slow-growing but eventually large, berries on female plants

Best Evergreen Shrubs for Chalk Soil

Chalky Chiltern soils (pH 7.5 to 8.5) suit most evergreen shrubs, with the exception of acid-lovers like pieris and some rhododendrons. These are the best evergreens for chalk:

• Photinia, loves chalk, red new growth
• Choisya, loves chalk, scented flowers
• Pittosporum, loves chalk, good for clipping
• Euonymus, tough, variegated varieties brighten shade
• Viburnum tinus, loves chalk, winter flowers
• Rosemary, herb, but works as a small evergreen shrub

Best Evergreen Shrubs for Clay Soil

Clay soils in the Vale of Aylesbury, Didcot and Bicester need different evergreens. These tolerate wet winters and dry summers:

• Viburnum tinus, tolerates clay
• Mahonia, tolerates clay
• Pieris, needs acid soil, common on clay in Berkshire
• Laurel, tolerates clay, large leaves
• Holly, tolerates clay, slow-growing

Tips for Planting Evergreen Shrubs

1. Plant in autumn or spring when the soil is warm. Avoid planting in summer drought or frozen winter ground.
2. Water regularly for the first season, evergreens transpire through winter and need moisture even when dormant.
3. Mulch annually in spring with compost or bark to retain moisture and suppress weeds.
4. Prune after flowering for flowering shrubs, in spring for non-flowering shrubs.
5. Feed in spring with a balanced fertiliser like growmore or blood, fish and bone.
6. Space plants properly, check the eventual size and plant accordingly. Crowded evergreens never look right.
7. Plant in odd numbers (3, 5, 7) for natural-looking groups.

Common Mistakes

• Planting too close. Evergreens need space to spread. A photinia wants 3 metres, not 1 metre. Check the eventual size before planting.
• Planting acid-lovers on chalk. Pieris needs acid soil. On chalk, use skimmia instead.
• Not watering in the first year. Evergreens die quietly in their first winter from drought. Water weekly through the first growing season.
• Over-pruning. Most evergreens need only light pruning. Hard pruning ruins the shape and can kill some species (phoenix palms, pittosporum).
• Planting all the same species. A border of all photinia looks dull. Mix 3 or 4 evergreen species for variety.

Frequently Asked Questions

How far apart should I plant evergreen shrubs?

Check the eventual spread of the plant and space accordingly. As a rule, plant at 60 to 80 percent of the eventual spread for a filled-in look within 3 years.

When should I prune evergreen shrubs?

Flowering evergreens (choisya, mahonia, viburnum) prune after flowering. Non-flowering evergreens (pittosporum, photinia) prune in spring. Avoid pruning in autumn, as new growth will be hit by frost.

Will evergreen shrubs grow on chalk?

Most will. Photinia, choisya, pittosporum, euonymus and viburnum all thrive on chalk. Avoid pieris, camellia and rhododendron. See our chalk soil planting guide.
