Architectural planting

Architectural planting that gives a garden its bones

Architectural planting for country and town gardens: clipped yew and box, pleached trees, bold foliage and grasses that give a garden strong structure all year.

Flowers come and go. What holds a garden together through the year is its structure: hedges, clipped shapes, trees and plants with strong, sculptural form. This is architectural planting, and in winter it is what you see.

What we mean by architectural planting

Architectural plants are chosen as much for their shape as their flowers. They fall into a few groups, and most good gardens use all of them.

  • Clipped evergreensYew, box alternatives, holly and phillyrea cut into hedges, domes and blocks.
  • Trained treesPleached hornbeam and lime, cloud-pruned shapes and avenues of clear-stemmed trees.
  • Bold foliageRodgersia, melianthus, fatsia, cardoons and acanthus for drama.
  • Strong seedheadsPhlomis, eryngium, teasels and grasses that stand through winter.

Structure and softness

A garden made only of clipped shapes can feel severe. The best effect comes from contrast: loose, airy perennials and grasses moving against dark, solid hedges. The hedge makes the planting look lighter; the planting makes the hedge look crisper.

Plant for February first. If the garden looks good then, it will look wonderful in June.

Architectural planting in the country

In a large country garden, structure creates rooms and frames views. A yew hedge with a gap cut in it becomes a doorway to the landscape. An avenue of trees leads the eye to a distant point. Mown grass shapes against long meadow are architecture made out of nothing but a mower.

Architectural planting in the city

In town, a single multi-stemmed tree, a run of pleached trees along a boundary or a group of clipped domes can give a small garden real presence. Because these elements are evergreen or have a strong winter outline, they keep the garden looking designed in every season.

Looking after structure

Clipped plants need clipping, usually once or twice a year. We specify plants that suit your soil and the time you have, and favour box alternatives such as Ilex crenata and yew where box blight or caterpillar is a risk.

Questions

Architectural planting FAQs

What are the best architectural plants for a small garden?

A multi-stemmed tree, a few clipped evergreen shapes and bold-leaved perennials such as fatsia or rodgersia give a small garden strong structure without taking much space.

Should I still plant box?

Box blight and box tree caterpillar have made box unreliable in many areas. Yew, Ilex crenata and Euonymus japonicus are good alternatives for clipped shapes and low hedges.

How often does topiary need cutting?

Most yew and evergreen topiary needs one cut a year in late summer; fast-growing hedges may need two.
