Formal garden planting: symmetry and elegance with perennials

The charm of a formal garden

A formal garden radiates order, calm and timeless elegance. Think Versailles in pocket format: symmetrical lines, crisp hedges and a clear structure visible throughout the year. The beauty is you do not need an estate. Even a town garden of five by eight metres can look formal and refined.

Combination 1: Box parterre with lavender

The heart of the formal garden is the parterre: low hedges forming geometric patterns. Use Buxus sempervirens 'Suffruticosa' (dwarf box, 30 cm, clipped) as the edging structure and fill the compartments with Lavandula angustifolia 'Hidcote' (lavender, 40 cm).

The combination of dark green box with purple lavender is one of the most classic images in garden architecture. In winter the box provides structure; in summer the lavender fills it with colour and scent.

Combination 2: Rose beds with yew hedges

Taxus baccata (yew, clipped to 120 cm) as a background hedge with a row of Rosa 'Iceberg' (white floribunda rose, 100 cm) in front. At the base, Alchemilla mollis (lady's mantle, 40 cm, lime-green flowers) as soft underplanting.

White roses against the dark green yew screen are breathtaking. In autumn the roses produce hips and the yew retains its colour — a strong winter combination.

Combination 3: Hydrangea borders

Two rows of Hydrangea arborescens 'Annabelle' (smooth hydrangea, 120 cm) on either side of a garden path, flanked by Buxus sempervirens balls (40 cm diameter) at regular intervals.

This is formal in a soft, romantic way. The enormous white flower heads of 'Annabelle' bring drama, while the box balls provide rhythm and structure.

Combination 4: Clean lines with grasses and alliums

Not every formal garden needs to be classical. Combine Taxus baccata blocks (clipped to 80x80 cm) with long rows of Allium 'Purple Sensation' (ornamental onion, 80 cm) in spring and Calamagrostis x acutiflora 'Karl Foerster' (feather reed grass, 150 cm) in summer.

The sharp yew blocks contrast with the loose grasses — modern formal. In winter the dried grass plumes sit decoratively above the evergreen yew.

Design tips for symmetry

Always plant in odd numbers per species, but mirror the planting on each side of the central axis. Use identical pots with identical plants as entrance markers. A central focal point — an urn, fountain or specimen tree — reinforces the symmetry.

Keep paths straight and edging sharp. A neglected formal garden looks untidy; a well-maintained one is elegant. Clip hedges at least twice a year: late June and late August.
